You mean the same IBM who couldn't scale the 750FX to 1GHz?
IBM is pushing the POWER5 very hard to bring it to the market as soon as possible, jan/feb 04 seems to be the timeline now (Itanium2 is the name of the game).
There is no pressure like that for IBM with the 980. But I have no doubt we will see it in a POWERmac (I like that, thanks LBB) only a 3/4 year later.
BTW the POWER5 is claimed to be 4times as fast as a POWER4 when it was introduced. So don't expect more...
