I think it's a good idea for people like yinyin to ask--not too early, not too late. Not saying there's any hope for the class of 2006, but getting prepared 2 years in advance is not a bad idea, especially since the class of 2007 are about to start Yaer 11 and get serious about their work (that is, if in their schooling career they haven't already). The class of 2006 are already one term through and should be motivated by this stage already.
Besides, it's good motivation! A nice trophy...mmm...I've never gotten one, and to get your few seconds of fame...mmm....
