The emulator/JIT (Rosetta) is just one part of the migration strategy.
The other (equally important) part is the ability of Xcode 2.1 (which
developers have now) to make what are called "Dual Binaries".
If you're developing an application in XCode you tick a box and the
executable it produces will run on *both* PPC *and* MacIntel.
Developers I know are already producing dual binaries.

No, Apple is shifting the whole product range.
