I believe Ed Zander, president of Sun Microsystems Computer Corp. hardware unit will be the new CEO for SGI. He turned down the Apple post because Jobs wouldn't quit off the board, and he's got the credentials .
As for someone saying Sun would be a good candidate to takeover SGI. Java, plus they've got so much going for them , having SGI wouldn't help much. It'd be a dead weight for Sun.
Having Zander as CEO ,would be a super plus in righting this ship.
