For those that are cancelling, surely it's better to hold on to it to sell on at Christmas?
I don't think there'll be huge demand after the initial flush of early adopters. Very few exclusive next gen titles will be out and devs are doing great things on the existing generation.
I might be wrong, but I'll be amazed if people are prepared to pay much of a premium for these things. However I am regularly amazed at what idiots will do, so they'll probably be on Ebay for a grand the day after I cancel my order.
I'm struggling to find anything else I want though. I'd be tempted to go XBO/Forza instead if it wasn't for the stupid wheel restrictions. That's why I went PS3/GT5 in the first place.
I do find myself wondering whether GT6 is a factor in all this though. If preorders were poor and it looks relatively poor compared to Driveclub, pushing DC back a few months may make financial sense, especially if you throw in potential early network issues.
