Snow Leopard will only work with Core 2 Macs and above, too, so if you don't have one, tough luck.
I presume this is pure speculation presented as fact?
Yes, based on what we've seen in betas and been told about the OS.

Now you've had some pretty crazy predicitions, but I think this one takes the cake. You can't honestly tell me you think that Apple would release a product that was not only not compatible with PowerPC Macs (which is at least believable), but also the first generation Intel Core Duo systems that were part of the initial Intel Macs.
We've been told that Snow Leopard is a 64-bit OS. Core Solo/Duo chips are 32-bit chips. Core 2 Duo chips are 64-bit chips. Nehalem is 64-bit.
There is a 32-bit compatibility layer in the betas of Snow Leopard, existing, I believe, because:
1. Apple hasn't finished porting everything to 64-bit yet.
2. The beta runs on all Intel processors, meaning they knew that they didn't have everything done in 64-bit yet and so gave 32-bit users a chance to debug for a wider base of use.
