I don't think i've seen this asked yet, which series do people believe is more future proof? That is the biggest underlying factor to which is the biggest franchise.

Interesting. I'd say, right now, neither franchise has shown a serious decline in tallies. They're both strong for the future. Unless Halo 4 doesn't clear 10 million, which is highly unlikely, both are good to go.

Ditto. Both should have one or two 10M+ seller(s) next-gen
