According to a new PDF file which can be found at mosr Motorolla's current powerpc architecture can eventually take them to 3ghz+ but their current roadmap only takes them to 1ghz with the7455 . We will probably be seeing that chip in the future imacs, and maybe powerbooks too. But they say "G4+" which means they don't have any plans to stop working with apple right away, as G# is a name that Apple gives, not motorolla. But will Apple use them all the way to 3ghz or beyond? If not how slow is moto gonna have to advance to get dropped? I am not seeing a real great processor in Apples future (If they adopt the 970 they might pull ahead eventually, but they will only be equal at the start), but Apple really needs some great product if they want to keep alive.
