Who actually believes that GT series IS more popular than Halo series.

[Slimebeast]

Halo has surpassed GT as the biggest franchise on HD consoles.

I perdict Halo 3 will sell 12 million copies lifetime, and Halo 4 will sell 15 million copies.

Gran Turismo is stil a huge franchise though. I perdict GT5 will sell 7.5 million copies.
