Considering even a portable gran turismo has more cars than Forza im presuming Gran Turismo 5 will have even more. Graphics look identical to me. Gran Turismo on what we have seen will most likely be the better game and obviously the better name.

Forza M 500,000
Gran T 1,000,000

Those would be awful sales for Gran Turismo 5. It will probably do more than that in Europe alone. Gran Turismo 4 sold 2.47 million first week.

I thought 1 in 23 people buying it in the first week was generous. Gran Turismo isnt as popular as it use to be and with this reduced install base it could struggle to replicate past Gran Turismo sales..
