As to if people will change the releases... why?
I'd prefer that they didn't.
If you launch the XBLive stuff from the new releases... E.G. NBA2k3, etc. and have a replacement dash, your MS dash gets nuked, period.
If you leave the MS dash in tact, your xbox merely gets the XBLive tab added and receives a new dashboard.
The next time the software is run, it knows that the update has already occured.
If you then rename things so that Evolution-X is the default dash, you'll get nuked.
HOWEVER if you use a ybox bios and leave the original dashboard alone, this does not happen.
The key is if you have a replacement dash or not and what it is called.
This has only little to do with the mod chip itself.
