1. Yeah it is very possible it wont sell 10+. However Halo 4 was tracking above Halo Reach up until Xbox One released hurting its legs. It certainly did not have poor legs though. Even then its very likely Halo 4 has outsold Reach if you include digital, and who knows how that compares with Halo 3 numbers if you count digital as well condsidering digital was much more popular once halo 4 was out compared to halo 3
2. Weird you talk about Halo not being a 10m franchise but then go on to name Gran Turismo and Mario. Have you looked at the recent installments? Gran Turismo 6 is at 2.41m, New Super Mario Bros U is at 4.16m, and Super Mario 3D World is at 2.21m. So using your logic, then these games arent 10m franchises either. Though to be fair Mario will continue to sell as WiiU continues to sell. Reaching 10m may or may not happen
3. XBO is down in america and Europe, no doubt. Then again Halo pushes consoles, thats a fact. 7m is very possible, but i want you to remember Halo 2 sold 7m on 25m consoles. It really depends on how well XBO sales to whether it will be near Halo 4 or Halo 2 numbers
