I'm sure that Mathematica was already compilable both for Intel and
PPC. Contrast that to an app that has never been run on an Intel
processor before.
The "tweaks" are mostly identifying and correcting endian issues
(byte ordering for longs and short ints, which are reversed on Intel
and Motorola processors) when data structures are written to or read
from disk.
If your app uses CFPreferences and never writes data in memory to
persistent storage, your "tweaks" will be minor.
If you write any data structure that contains entities that are > 1
byte in length, your porting time will be longer... maybe much longer.
And then there is the deprecation of QuickDraw and its eventual
elimination from Leopard a year from now.
I know I'm going to be busy for a while!

Actually, I'm pretty sure Steve implied as early as January, no? I'm
guessing the announcement will come at the Jan conference, and then
ship in 3 more weeks or so.
It'll be fun to see the reports on which developers compiled their
source into a Universal Binary with the necessary tweaks and how
long it took them (compared to Mathematica).
