3.0 hardware

Hi All, I have an 2018 Model X with Enhanced Autopilot and I debating if I should upgrade hardware from 2.5 to 3.0 - what will I get if I do that other than $1000 out of my pocket. Did anyone do it? Does it make sense to see if 4.0 comes out. FSD upgrade for me is $6000 so there is also that...

I looked for any threads that might have clues but found none. Forgive me if I missed it somewhere. Maybe there simply is no answer yet... For those of us with AP2.0/2.5 who bought into FSD (with the promise that our hardware would be upgraded to 3.0), is there any clue out there when it will...

As an EAP owner (got car in December 2018) I want the new 3.0 hardware. I know it won't change what I have immediately, but it will. I want to help Tesla keep developing the technology. But at what price, after EAP already cost me $5k?
