Which Digic chip is it (Digic 2, Digic 3, etc.)?
LOL Digic 2 and 3 are LOOONG gone! They introduced Digic 4 back in 2008, and pretty much all Canons have been using them ever since. Which stinks, because a lot has changed in digital imaging since '08, yet they haven't upgraded the architecture.
Back then, I don't think they expected to be pumping 1080p through the compressor, and so they've had to cut corners to still be using it.
We're all anxiously waiting for Digic 5, which should hopefully alleviate many of the current issues.
As for pricing... I haven't been watching the consumer market, but I know that Amazon's prices on Canon and Nikon DSLR equipment has actually shot up $50-$100 since the Japan disaster. Rumor is some manufacturing plants have had to close for now, which is going to effect the supply versus demand.
