Yeah I find it a bit nutty as well. On the high end, things seem fairly under control. There was 1DsIII and the 1DIV (one is full frame the other is ASP-H 1.3x crop, each suiting a particular niche of pro-work) (now both are apparently being merged into the newest 1DX) then there is the 5D full frame line, and then the 7D high end ASP-C 1.6x crop camera. Now there is a 60D right behind the 7D, and then way too many Rebels... And while there are differences, there aren't a whole lot of major features differentiating the various cameras between the 7D and the rebels and even the newer rebels that replaced the older rebels, it's a bit wasteful (seemingly) to say the least, but this doesn't come as a surprise as almost everything about our various monetary systems leads to quite wasteful and inefficient means of distribution as profit is always the underlying core value and motive. I also wish they would start naming the Rebels in the US like they do in Japan and Europe etc., 650D, and so on, instead of Rebel T2i, etc., if I ever bought one, I'd import it just for that (yeah I know, a bit vein but, oh well)
