What else could you be talking about?
No G6, O RLY?
New PC arcitecture? OH, you must mean the Intels, that are a different arcitecture than the previous Gx processors. Not to mention that they are "PC" architecture. The Intels are new, they replaced what would be the G6. The next set of Apples will be the next revision of Intels. Core 2 Duo and Core 2 Solo, A.K.A. Conroe. And yes, they will probably be out by the end of the year. My guess is the Intel Powermac will be Core 2 Duo. I expect it will be out in August.
