Could the base install be a 15kW charger with a service center installed additional 5kW charger for the same 20kW of power? For people without two EVs 6 hours of charging would almost always be quick enough for nighttime charging.

Tesla calls it a 10 kW charger because it sounds cooler than 9.6 kW. And yes they use 250 V as the basis for that claim since voltage can vary from 240 V, but no you are not likely to get 250 V in the US. But the charger would support it if you could ...

But it may actually be a boost for the vast majority of owners (if the vast majority never buy the dual charger option).
I'm not going to stress over this rumor. This is very unlike Tesla, typically they improve charge times, not lengthen them. They may have created a larger single charger, but I'd be surprised if they still don't provide a 2nd charger option. Or if they remove the double charger, then it would be replaced by an equivalent single charger option. Either way, whatever change they make, I would expect that the charging times will remain the same or improve.
What about all the money Tesla has dumped into giving away HPWC for the Destination charging program? Model X would not be able to take advantage of the full capability of those systems. I got dual chargers with no intention of using them at home. Since that time, Tesla has given HPWC to several places I like to go in eastern Oregon and I've used them many times. Model X should be an even better road trip car. As Teslas become more an more common, fast charging at destinations will be more important so more vehicles can be charged on the same equipment in less time.

Perhaps there is another reason for not offering the dual chargers. There has been a suspicion for a while that rapid supercharging could hurt battery lifetime. For a good report on this, see
Life With Tesla Model S: Does Supercharging Cut Battery Capacity?
It occurs to me that Tesla might be trying to limit extremely rapid charging to maintain lifetime of their batteries. This even occurred to me when Elon came out and said that they might limit people who were using superchargers for local charging. Tesla can't really come out and say that this hurts battery lifetime, as they have denied it for so long, but perhaps they will try to discourage it except when necessary.
60 amps charging would definitely preserve battery lifetime over 80+ amp charging.

I think we have a winner! The only way adding a bigger single charger to the car makes sense is if it can be used with the UMC that's included with the car. Going from 14-50 to 14-60 allows use of the highest amperage plug commonly available, thus allowing the larger battery to charge faster.
Supercharging bypasses the onboard chargers though, for one. For two: I could see Tesla better educating consumers or better handling the charge curve to protect the batteries, not SLOW DOWN a process they're touting as fast (and have been making faster).
Perhaps, but don't hold my hand. Make me aware of the downsides of doing something and I'll make my own decision as to whether or not I'll do it, and how often.
Hopefully we get some clarify tomorrow.

I play a nice person on twitter.
That's how it's set up for Roadster owners when selecting charge mode - you are notified that what you're doing could potentially shorten battery life and you confirm that's what you want to do.
80 amp charging is 60 miles per hour vs. 200+ miles per hour for supercharging. I really don't think the next 20 amps is going to make that much of a difference.

If Tesla is about to introduce a new, higher-grade charger in the Model X that can take 60A... that would be great. Destination charging connectors supplied by Tesla after this introduction would obviously be capable of supplying two at that new power rating (so... 120A). Older Model S cars like mine would only draw 80A maximum from this newer connector.
Perhaps the HPWC will be upgraded to supply 120A. If this occurs, we shouldn't be too surprised if it comes with a water-cooled cable that has a "hum" rather like a water pump in a tropical fishtank
The current HPWC has a design issue that causes the handle to get very hot sometimes - too hot to touch. Perhaps there will be a two-tier HPWC product range.
Lyon... all destination chargers would still work, they would supply 40A, 60A, 80A or 120A depending on what your car draws from it.
Don't forget that the Model S and the Model X share the "Generation 2" platform. Perhaps the Model S will be upgraded to 60A charger(s) too.
The only thing I am worried about is that Tesla will want to phase out (no pun untended) the second internal charger altogether... and only go with 60A maximum current. That sounds scary. I love charging at home using 80A. I've been concerned to see them de-emphasise the 2nd charger like they have, I've never really understood it. I refuse to believe they can't "fit" a second charger into the Model X - a vehicle that has even more storage space than the Model S.

And if you max charge 2x on a Model S, the next time you get in the car it alerts you of the same. I would think that's more than sufficient. I can't see them engineering a roadblock just to stop faster charging.
