As I was reading the article, it just got worse and worse. If, but's and maybes. Verifying rumor one by refering to rumor two and a preliminary spec.
A G3 running >1GHz using 0.10 micron integration and featuring the altivec..? I mean, that's a "G5" ;-) Sorry lads, it's probably just another far fetched rumor.
In any case you won't be using anything new anytime soon in your Peggy/A1 anyway.
