Profile 2.0 - Re-release Blu-rays?

[Yuzo]

i was reading up about players and discs upgrading to Profile 1.1,.. and then maybe 2.0?

i know studios re-release their discs when they find another extra to put on the disc "cough, cough Blade Runner", which can be annoying when you have just payed full price for a now outdated copy.

but when players do get all this fancy Profile 1.1 or 2.0 with PIP, etc. will these "early" release discs become obsolete?... will the studios re-release all of their discs when they start releasing newer discs with higher profile capabilities, and extra cool features?

i was also happy to read that the PS3 is capable of upgrading profile via a simple update
