Hi I'm new to this forum although not at all new to this topic.
I agree with SiliconAddict. PB G5s (or at least PB with some new architecture) have to come out soon. Now here is my little theory:
dual-core G4s would be nice but they will not make it. The chip isn't out yet. Not even the single-core version AFAIK. So there is no way this is going to happen.
A simple speed-bump to 1.6 or 1.7 (thats at least what the rumors say) and keeping the 'old' G4 (MPC7447) would IMHO not result in an EOL. There are signs that all current models are sold out. I can't remember that this was the case with the last speed-bumps so I'm not going to buy that either.
Also if it really is EOL and they are making new cases for the PBs then this means something bigger is happening here. Convince me wrong but I don't think such a revision would last long and would not be very lucrative if they had to do another new case for the G5 until september.
And BTW: releasing something like this would be very embarrassing when at the same time Intel releases their Centrino 2 systems. So I at least hope that this won't happen!
Another possibility would be that they are going with the G4 MPC7448 with a new architecture and 200 MHZ FSB. Well thats possible for sure but at 1.6 or 1.7GHZ they wouldn't be a match either for some P4 2.1GHZ with 2MB L2 Cache.
So IMHO going with the G5 or some derivate (970GX maybe??? =lower voltage + lower heat) is the only option for Apple. Also a G5 1.6-1.7 would make sense. At least to customers it would look like a high gain in performance, simply because of the G5-effect alone
Now for the timing of the release:
I believe that Steve wouldn't even want to announce a PB at MWSF05 because that would have ruined all the good press for the mac mini and ipod shuffle. They would have been over-shadowed by the PB G5s.
But now these products have been in the press all over the world. Apple achieved its marketing goal.
Furthermore I believe that Apple, due to the (at least to me) surprising release of the centrino 2, feels hard pressed to release at least some-kind of upgrade to their mobil pro section. Maybe they wanted to do it on WWDC in June but lately decided to do it earlier.
So my hopes are high that we'll see the PB G5 soon!!
P.S.: Anyone knows when the 970GX will be ready for deployment? Cuz I'd love to see it in the upcoming PB!!!!!!! well a man may have dreams...
P.P.S.: This was my first post here so don't be too stern on me
