Roy, I haven't got a f**king clue how they've managed to stay afloat!!
There aren't many companies who can set their own dates, the big one which springs to mind is Valve, but that's about it.
I'd love to know what the holdup is. I'd imagine all assets were signed off by the manufacturers months ago, if not years in the case of some fo them! That's a massively time consuming process, and they have a hell of a lot to get signed off.
If they are still in dev, then they've got QA time to add, plus submission which is going to be the best part of 2-3 weeks, then there's manufacturing. I'm sure with the muscle of Sony behind them they can push some of those things through a little quicker though, but not by much.
