Um, heh. You're demanding a dual processor iMac with a 17" LCD monitor. Get real.
It'll never happen, until like 2005 when Apple totally revamps the iMac again. (Hmm, maybe a pyramid?)
Although I do agree that a 17" CRT is bigger than a 15" LCD. But the benefits of LCD are that it's twice as sharp and twice as bright, and it's easier on your eyes, not to mention it's more environmentally friendly since it uses up much less power. And of course it's so much smaller. Imagine having a 17" CRT on the end of that swivel thing. Hahaha that would be funny.
