Blizzard don't make good games... they make the best games...
But I have to agree with Shio's argument that the PC is seeing much more console games comming.... However, I believe that this is due in part to the fact that the X360 is an easy jump to the PC.... similarly, it's also why all these publishers came to consoles.... look at Epic and Valve that stay axed on the X360 rather than supporting all HD.... the 360/PC is a good combo for them as the increase of costs isn't significant.
Basically the publishers shifting one way or an other is a moot point due to consoles being much closer to PCs than they ever were in development terms.
About the sales... well yes it is impressive to see these boosts, though numbers sure would help. One this is sure though is that the ME1 poping back up is damn impressive.
