If you combine both sales of origina Halo 3 and ODST so must combine both GT5 and GT5P. GT5P soon will be 3mil. It should be around 3.5mil when GT5 released. I expect GT5 will sell at least 8-9mil. So total would be 12.5mil. Halo 3 OSDT will sell at least 3-4mil. So both will be very close. PS3 might has less userbase but GT4 has much lower sales than GT3. So if GT5 it sell well. Final Fantasy and Metal Gear also same.
