Going by their numbers without Trump, it looks like most of the major candidates are in decline. Gingrich, especially, is looking like he might actually fall behind Paul. Palin has been slumping too (apparently because Bachmann is looking like a better option), and Romney would appear to be declining slightly too. The only candidates near the top who aren't falling are Huckabee (who is rising, but still doesn't seem especially inclined to a run) and Paul (who has been holding relatively steady for the past while).
Actually, none of the changes seem particularly significant. No one really seems to be going anywhere. Which might explain why Trump could get in and gain a lot of voters.
