I feel MS fell into the same routine Nintendo did by leaning only on 2 or 3 franchises so much (Gears, Halo, Forza for MS and Mario, Zelda for nintendo). Of course Nintendo has been in games much longer so it took a bit longer for them to realize where the money was and abandon things like Metroid, Donkey Kong, Kirby, etc.
Scalebound looked bad, and I guess they saw how Re-core did and decided it was for the best.
I'm not sure what xbox players want from MS in terms of games. Do they want them to stay the course and give more Forza, Gears, Halo? Do they want MS to bring back the oldies like Fable, Viva Pinata, PGR? Or do they want MS to dump everything and just give them new IPs like they did back at the launch of the xbox and xbox 360?
I don't know what the future holds. But I hope the scorpio bring something new to the table. I want more Gears and Forza but I want some variety too....
