Just seen this.
I think it's a good idea from their POV. Although, if they RRP'd it at 350 quid it would make more sense - the current RRP isn't THAT distinct from the 450D and if there is one thing photographers are good at it's wanting their camera to do more and do it more efficiently (which would make the 450D a viable and sensible entry-level camera, even with the introduction of the 1000D).
But the more people they hook with good value entry level DSLRs, the more people will end up buying 60Ds in the future!
And the more people shooting with an SLR the better as far as I'm concerned, it's a hell of a lot of fun.
