Does this mean I should have bought an XBox instead? Yeah, maybe, but too late.
I based the backwards-compatibility speculation on the graphics processing unit that Sony is probably going to be using for Orbis. It would require a complicated and expensive additional hardware to add a proper emulator, even more than what was needed to emulate the PS2 (a feature that didn't even work for all games, and was dropped from production relatively quickly). Yes, everything is pure speculation at this point, but I don't expect it to be backwards compatible, so I'll be keeping my PS3 hooked up for a while. If it turns out to have this feature after all? Hey, nice bonus.
My speculation on not being able to transfer DLC includes not just the track record of Harmonix (stellar!) but also of Sony (... not stellar?). I expect Sony to make it a priority to hinder pirating, and modding, and even the used game market, and I expect their efforts to have the effect of making this transfer impossible. Might I be wrong? Sure! That would be nice if I was.
And no, you can't use a PS2 controller on a PS3, there's no similar port on the PS3. There are 3rd-party adapters to try and work around this, but the one I saw in action kept timing out in the middle of action. I went ahead and bought my cousin a real PS3 controller, because it was just sad to watch.
