Could Halo Wars possibly outsell the much more hyped KZ2 in first two month

[TacoBoy49]

Why would Halo Wars not have long legs? Halo 2 and Halo 3 had incredibly long legs. Halo 3 is still selling like it was launched last November. MGS 4 ran out of breath after 2 short months. Halo Wars will sell for a long time also. Halo brand is evergreen like Mario.
