Well It's sold through 750k units and probably shipped a million or more. It's also being bundled in the winter with Forza 3 in Europe as a digital download versus a retail disc - so yeah it was a success, just not as large as everyone was hoping for (then again for It's genre I think people expecting 2 million in It's first year is a bit absurd).
If theres a Crackdown 2 on the market there should be a Alan Wake 2 on the market as well.
Games that have done worst then Alan Wake, or Alan Wake will surpass with the same time on the market, exclusive to or timed exclusives for the 360/helped by MS:
Ninja Gaiden II .97 Million (thought this was published by Tecmo but VGChartz says Microsoft. I know Bungie gave it a slight push with the Hybusa armor in Halo 3.)
Lost Odyssey .84 Million
Too Human .70 Million
Banjo Kazooie .70 Million (another Rare "flop" and was heavily bundled to)
Crackdown 2 .65 Million (Looks like Alan Wake will outsell it)
Infinite Undiscovery .59 Million (MS owned the name so it became exclusive)
Ninja Blade .22 Million
Blue Dragon .55 Million
Kameo .53 Million (This was also a launch title)
Shadow Run .42 Million
Viva Pinata 2 .39 Million
VP Party Animals .18 Million
It's gonna be a tough sell to get Alan Wake in the top 10 sellers published by Microsoft, but re-using the same engine with some tweaks and a small development team it should easily be a profitable venture to release Alan Wake 2 for the 360.
It's just that simple.
