According to Ars Technica, specs for the Nintendo Revolution have been outed by a Factor 5 employee going by the name (get this) Hans Solo. But if you can get past this guy's being trapped in the past, he is also said to have leaked the Xbox 360 stats before they came out, so I'm prone to at least listen.
"The brains of the console are rumored to be a single dual-threaded IBM "custom" PowerPC 2.5 GHz CPU, with 256 KB L1 cache and 1 MB of L2 cache (L3 cache is rumored). The system will also sport a Physical Processing Chip (PPU) with 32MB of dedicated RAM, while the CPU itself will saddled up next to 512MB of system RAM. The custom ATI GPU solution is rumored to consist of a RN520 600MHz core, backed with 256MB of RAM and "32 parallel floating-point dynamically scheduled shader pipelines." While the output will theoretically be capable of putting out 1080p resolution (higher even, at 2048x1268), Solo says that HD support has not yet been decided."
Solo also mentioned that Revolution may even have an edge on the 360 and PS3 in the CPU/GPU area.
Update: Factor 5 president Julian Eggebrecht has, not surprisingly, denied everything.
"Han Solo is a scoundrel, we all know that, but in this case he isn t
a very clever scoundrel. That so-called employee of ours posting on
message boards under the Han Solo name certainly isn t employed at
Factor 5 or working in any way for us. He isn t speaking for the
company and he better change his story as to where he has his
information from, or we will be forced to take legal action against
