+1 to Gordon's rant
Anyway, similar thing's happened in the Nikon line in the last few years, The D40 came and then its successor was the D60 because, actually, there was the D50 that was (sort of) the D40's predecessor, AFAIK, nobody complained.
In fact, a bit later, Nikon ditched the DXX nomeclature from its entry level line because the successors of the D60 were the D3000 and the D5000, probably because there also was the venerable D70 and they couldn't use that name again.
But that's not all! The D90's successor it's rumoured to be called the D7000 (Yes, you got it, there WAS a Nikon camera called D100 before the D90
Come on people, who cares about how it's called? I think the 60D is bound to be a great body and has an impressive array of features for its intended market, as Gordon says: Not enough for you? Well then, go for the 7D or the 5DMk2.
