Gears and Halo3 sales

[Seece]

Halo franchise is over 25 million sold, Gears now 10 (PC?)

By end of this generation if new Gears is out then I expect Gears Franchise to be above 25M and Halo to be 50M (what with Halo Wars, ODST & Chronicals)

75M from two fairly new franchises is nothing to be sniffed at.
