I can see it being £24.99, same as GT5P tbh. GT5P has 6 tracks (5 in the JPN orignal before Xmas version.), the offline is not very big, online is not very good, not private lobbies, friends filters, etc etc. I really can't see it being any less then £24.99, that said, I would pay double that for 8 tracks with online private lobbies.
Don't see the point in making death threats mate btw, Sony, MS whoever, they always shaft their customers (even more so us in the UK), been doing it for years and I can't see that changing anytime soon.
