I know nothing about Canon's product release cycles. Is now a good time to invest in this puppy? Or will the 5D Mark III or some such thing be out soon?
The 5D Mark II came out at the end of 2008. The Mark III is widely rumored, but hasn't been officially announced; most people are guessing it will arrive toward the end of 2010 or early 2011. canonrumors.com has lots of this kind of speculation...
