A few points here...
Yoxxy - Expecting that "a new chipmaker will come out from the ashes" is quite unrealistic. The reason that the other CPU makers are so low in marketshare is that the "barriers to entry" on CPU manufacturing is so high. To be financially competitive in anything but a niche processer, a rival would need to own at least one cutting edge Fab.
IBM
could do it, but if you look closely you'll note that they're scaling back significantly on their microelectronics business.
To even think of challenging Intel at this point, you'd need a good $15 Billion in cash, covering Fab building, R&D, and running costs for the 3+ years it would take to build and ramp up...that's quite an investment for something that unsure.
Edit - Damn...IDC beet me to it!
waffleironhead - I think you misunderstand what a Monopoly is...
"A monopoly power is defined as the ability of a business to control a price within its relevant product market or its geographic market or to exclude a competitor from doing business within its relevant product market or geographic market. It is only necessary to prove the business had the "power" to raise prices or exclude competitors. The plaintiff does not need to prove that prices were actually raised or that competitors were actually excluded from the market"
Business Law Definition
Duvie - No, I don't think you were j/k at all...even better, you were correct!

As to the speed, remember that the really big suit still doesn't happen for 1 year (April 2009). I don't expect a settlement until near that time (and I DO expect Intel to settle...they aren't stupid people). A settlement might cost Intel $4 billion or so, but a judgement could be in the $30-40 billion range, and allow the FTC and Justice dept to file as well, using whatever AMD digs up.
