I'd make a case that it is the weakest men's field I can remember. Plushy at the top, and the rest competing in a race to the bottom. The only question is Plushy's health and whether he has the same sort of mental Olympics-only glitch that he had in 2002.
Plushy (health problems, but unless he withdraws, a lock)
Buttle (consistently flawed, no quad, but is going to try one (thus spotting Plushy one fall in the LP))
Sandhu (even more consistently flawed, a head case)
Joubert (another head case)
Li (stamina problems, and judges don't like him)
Takahashi (head case, but young, he may get over it, no quad)
Lysacek (no quad, weak LP skating to Oh No Carmen, falls a lot too, worse, plans to try a quad (think Todd Eldredge as well as Buttle))
Weir (health problems, weak LP replaced for last year's LP,no quad but plans to try one

another one)
Lindemann (not skating well the last two years)
At this point, I expect a splatfest, but hope to be surprised by Wylie-like performances from men unlisted.above...maybe Preaubert or Dambier. (I love Preaubert's SP with the imaginary bee in it) or Klimkin. He skated a great LP at Europeans. If he hadn't done a waltz jump in the SP, he might well have medalled there).
If you want a really great men's field, I recommend watching the 1988 Olympics, particularly the SP. The results, of course, were influenced by figures. The top 3 spots were supposed to be predetermined to be the 3 world champions that were competing (Boitano, Orser, Fadeev, with the edge given to Orser), but if you look at the up-and-comers, you'll realize that if either Brian or Petrenko had faltered, there were good performances in plenty that could have been rewarded..
Here's who was skating:
Brian Boitano
Brian Orser
Viktor Petrenko
Alexander Fadeev
Grzegorz Filipowski
Vladimir Kotin
Paul Wylie
Chris Bowman
Kurt Browning
Petr Barna
Heiko Fischer
