Well, the company who made COD 3 had previously done COD games for consoles. No big deal really, as COD 3 really sucked and is the 'odd' games out in the series. One can only hope COD 5 lives up to expectations, as the same company who made COD 3 are making COD 5 (no idea why).
Ya, well i heard from my dads friends friend (hes working w/ the company to make COD 5) that it is going to be very graphic and very good, but all the producers say that about there games. The i hope for is that there is no lag.
Well its already common knowledge that they are using the same graphics engine as was used in COD 4, so graphically it should be pretty awesome looking. Lag has nothing to do with the game and everything to do with the hardware on your computer + internet connection.
I really am dying for COD 5. Though Treyarch has (apparently) said that after that, they are making no more WW2 games. I don't know weather that means they are leaving COD though.
