I work in engineering in a similar industry. For such a thing to happen, a 8-12 month delay, something got seriously fuu-d up.
It's certainly several months since the camera was announced, but the release date was always put there as March/April 2012. So really that's a couple of months. (So far!) I'd prefer they withheld the release until it's 100% right, even if it's post-Olympics. This camera can't be an anticlimax from Canon...it has to be an absolute killer. I'm enjoying most things about the 5D3, but just can't bring myself to cancel the 1DX pre-order.
