Here's another thing I am wondering about-- can you have two different copies (or in this case, versions, North America + PAL) of Wipeout Pulse associated with a single PSN account? Or would we need to have two PSN accounts (and hence a new username) to play the North American release?

I am perfectly happy to buy a North American copy of Pulse but it still isn't clear what all is different between the PAL and North American versions, plus what the implications are for PSN accounts... I suppose we'll get more info about this soon enough
