Of all those stating the MCU1 shouldn't have any problems running circles around the tasks it's given, would you care to enlighten me as to why it hasn't been doing this for the past 6 years?

I called the Decatur SC...they told me to buy a new car if I wanted the new MCU
After I mentioned the Tweet...They informed me they will look into it and provide me an update.Obviously the coming soon part is for the software and not the retrofit.
Like verygreen mentioned it’s very vague and he didn’t mention retrofit.

I would be happy even if the IC display isn’t upgraded, that would make the replacement a lot simpler but would require some custom code on the retrofit to output data to the old IC display. The old IC display is just fine, it is the main screen that is so slow.
Speed is one thing, compatibility with future enhancement is the most important thing I want with the MCU retrofit.
Let’s find out the cost before we celebrate.

Got an email back from the Shop Supervisor...I called the Decatur SC...they told me to buy a new car if I wanted the new MCU
“This is a new development and details on price and availability will be released as they are available.“
I typically find electronics don't like water, I once saw someone slam on the brakes to avoid an accident and in accidentally went all over the dash, imagine what would have it if went all into that poor little cid sitting right in the middle of the cup holders. I'd imagine it would not be good for the CID and just a tragic accident because you were trying to save that squirrel!
I'm not sure if an Elon tweet means [confirmed]
I'm still waiting for a lot of tweets to come to fruition.

I asked my Service Center about having my MCU replaced a few months ago before this new one was even a thing. They said it's $3400. I'm pretty sure this new UMC2 will not be less.
Elon has an amazing knowledge of the engineering details, so I'm sure he knows the swap is trivial. Now his organization (which btw must be tired of being overruled by Elon) will have to come up with a price and a upgrade ticket for those who want it

Am I the only one not thrilled if a successor to a 7 year old system only has double the speed? Should be much, much faster, no?

Oh wow!!! This would be amazing. I am totally ok with paying extra to get the upgrade. I would just be happy to get that new updated computer in my car. Fingers crossed. Hopefully Elon convinces the people lower down the chain to offer this as a paid upgrade.

Imagine everyone's surprise when they re-read the tweet after Elon says "hardware" was meant as a brand new car not the MCU...
Most likely is, but limited by software. Even the newest state of the art touch hardware can feel slow if the software has not followed in time.
Lots of smoothness improvements since 2010 on the mobile front (eg Android and Windows) is due to smarter software. For example making each touch event trigger hardware interrupts. The interrupt immediately pauses any current task and gives control to the application for that part of screen's UI thread for scroll/touch. User feels immediate response from the screen making the phone seem fast, altough the overall system efficiency is actually reduced.

Yeah, a flippant tweet from Elon is far, far from "confirmed." (who changed the thread title?). That means the SDK is confirmed. A Chrome browser is confirmed. AP2 cross country drive in 2017 is confirmed. FSD in "3 months maybe, 6 months definitely" is confirmed. Yadda, yadda, yadda.
So you said it yourself, the IC stands alone and relies on Tegra2, the CAN bus, and data from the MCU to function. Wouldn't it be easier to just port that software to send the IC the same data stream, then re-engineering an entire physical dash retrofit for every single car, including a new IC, wire harnesses, MCU, connectors, and I'm sure dozens of other parts? Or is the easier route to just build a drop-in MCU1 replacement that already plays nice with all the existing IC and hardware? I really don't know why you think an entire dash retrofit is the easier and less expensive option than porting some existing software?
Exactly.
Who said it was trivial?

I am absolutely stunned that Elon should offer this upgrade.
A moment of typical Elon brilliance
Just hope that the rest of Tesla are not just as stunned (oh cr@p did he just say that, all leave now cancelled)
(I'm sorry sir we cannot get your car in for service for 6 months as we booked solid with MCU updates)
Hey @Elon - give me the training and I'll give you a bunch of time to help out with demand for free just for the heck of it.

Non-trivial changes are usually not suggested by Elon. Such as AP1->AP2 (explicitly stated) or AP2>AP2 5 (never mentioned).
Ofcourse I don't know for sure until I've seen wiring diagrams for both MCU1 and MCU2, but it would surprise me if it was not a drop-in replacement. The software code for CAN interface is probably identical in both builds.
If the software is fairly reasonable written, the new platform was just a few new device drivers compiled into the linux kernel and a recompile of the firmware on a new target. More likely MS/MX with MCU2 still share codebase with MCU1, than share with M3 (yet, until all is unified).
