Don't you people have anything better to do than come up with lists of random guesses as to updates that might not even come??
If you do, I'm pleased for you, but I don't

So here's my list:
All updates will have Santa Rosa. NOT all will have LED displays.
New 13" MacBook white (spec boost, Santa Rosa, still integrated graphics but better than before)
New 13" MacBook black (higher model, better specs)
TWO new 15" MacBook Pros (with LED screens; two spec levels)
New 17" MacBook Pro (no LED)
That plus BTO would seem to cover the line.
I'd love to see a subnotebook (aka 13" MacBook Pro with LED screen, flash boot drive, and what the heck... 3G wireless!) but I'm not holding my breath. Yet.
