to be honest, i dont get that DS vs. Skyrim fight that just goes on and on for weeks now Oo but i guess its good publicity for from software, since we all know SKYRIM will do sell well, while the success of Dark Souls is still unproven. (Okay, i think we all can agree that it will be worth publishing for Bamco, but to what extent?)
however, seeing many 360 Sites hyping DS makes me happy. i guess 360 really deserved to be also hosting the spiritual successor to Demons souls. =]
i hereby predict the Sales of Dark Souls:
----------------------PS3 / 360
1 week WW: 250k/100k
10week WW: 400-450k/150-200k
LT WW: ------- 1,4-1,5m / 500-600k
i think it will sell pretty solid on 360, however PS3 will overshadow it by a lot. Why? I think the kind of Gamer that is into dark souls, doesnt rarely posess both Consoles. And since they have bought Demon's for PS3 since there was no other option before, they'll just continue to buy it for that system. the final number a year later for both systems combined is around 1,75m - 2,1m. (.. so funny, From Software was always a company, that wasnt really successful until now, and the SOULS games changed all that xD)
however, i'd be gladly proven wrong in a good way!
