current Powermac G5, or wait for intel...? ibook dumpoff...

Hello all. I am currently running on a ibook g4 1.33ghz, 1.5GB. I am looking into getting a desktop. The first since my mac switch a few months ago. However with the new intel rollout have there been any announcements about an intel powermac (or macmac pro?) lol.

I wouldn't mind waiting if were are talking within the year. I would wait it out. Next on the agenda... there are some rumors on new core duo ibooks rolling out in the spring. I want to dump my current ibook and use the funds toward a macbook pro. when would you say the best time to do this is? I don't want my selling to accidently coincide with the release of the new ones. thanks.
