That does sound interesting, I have to admit. Sports might, one day, be part of what I shoot. For instance, my cousin plays rugby, and I have told him I'd be shooting one of his games in the near future.
Currently I'm studying journalism, which I might combine with photography, and I think it's good to have gear of myself. Especially since most journalists tend to work freelance, forced or not.
However, the 5DII is not yet off the table. Not by a long shot

And to be honest I was indeed also thinking of maybe going for the IS version of the 70-200... I should be working again at Christmas for two weeks, so that shouldn't be too much of a problem by then.
