Apple doesn't really care much about backwards compatibility. I'm sure they will have an x86 emulator, but it probably won't be very fast (read: useless for games) and will probably be dropped entirely a few years down the line.

Depends on what you mean by "much". They have made good backwards compatibility an important part of every single architecture transition so far, and on the Mac there were good 3-4 year official transitions at least (the 68k emu still ran under Blue Box/Classic Environment so it lasted through 10.4 Tiger, Rosetta lasted through 10.6 Snow Leopard). And that's official, in practice there have continued to be longer last options.
It's certainly not the degree that Microsoft has traditionally cared, but it's not at all been blown off either.
