    It seems to be such a minor update, maybe we can still run Snow Leopard
    on those new MBPs? What do you think?
    Why would they block it?

    According to the genius at the apple store i just got my 15 it's not possible to put snow leopard on the revised 15 inch machines at all because of the new graphics cards. Possible only on the 13

    That sucks seriously. It would be zero effort to keep those compatible.

    The new MBPs are Lion-only.

    It would take a significant amount of effort, they would need to build in driver support for the new setups into Snow Leopard which would necessitate a new round of beta testing for a 10.6.9 update.

    Not going to happen.

    If the new 13" runs SL, maybe the low end 15" will.
    It's GPU is 7650M which had driver support in SL.

    Apple has never (correct me if I'm wrong because I don't think I am) introduced a new model (even if a speed bump) able to run a prior OS (in this case, Snow Leopard).

    I also bet that these new Macbooks will not run on the original Lion and will require 10.7.2.

    There may be a hack to get Snow Leopard to work on the 13" (or even the 15") but I'm betting a standard installation will not work.

    I'm sure we'll hear reports on this soon.

    I think a MC723LL/A factory restall disc will work for the low end 15"

    Check out insanelymac or netkas - both sites are populated by smart people who can bypass Apple's frequent oversights.

    I'd hate to be forced into Lion. I really hated it when I had my 2011 11" MBA.

    Just I my late 2011 MacBook Pro (low end).

    Can confirm that the retail OSX install disk (10.6.6) for the early 2011 works on this model....

    Did not install the new EFI before I tried this. Might not work with that one since it reads 10.6.8 and up.
