Sorry, I realised I was wrong after I typed that since I thought it came out in October. I couldn't be arsed deleting my post though and I humbly ask for forgiveness for my inaccuracy and laziness.

I still stand by my end point though. The PSP is selling well but apart from a few blockbusters like CC:FF7 it doesnt seem to sell any games unlike the DS. Mind you it could be down to people like me - I've owned a PSP since the European launch over two years ago but I've only ever bought 6 games for it.
