MS shuttered multiple studios last generation, didn't open any to replace them, and are now suddenly in a mad scramble to open studios and push out early XB1 titles.
Investing strongly on the doorstep of a new generation isn't a commitment to first party software. Expanding your first party studios and supporting the console you have out with major new titles through the launch of your new console is a commitment to first party software.
Case in point: I don't know who the hell even works at Black Tusk so why would I have any interest in a game they're making? I'm not eagerly anticipating the next game from Nihilistic and they've at least made something before.
Meanwhile I know what Naughty Dog brings to the table. I know what Sucker Punch brings to the table. I know what Guerrilla Games is capable of. I know that at worst Sony has damn near a dozen very strong first party studios that turn out at least "good" games, with several of them more than capable of hitting a home run every time up to the plate.
MS could have had something like that, if they gave a shit about first party development. Instead they let Bungie walk because they just wanted a Halo cow to milk (and now have one with 343 apparently). They sunk the PGR franchise by not picking up Bizarre Creations once they were outside the X360's launch window. Shut down FASA and let Weismann take the IPs with him. Doomed Crackdown to irrelevance when they chose not to sign Realtime Worlds up for a multi-game commitment. Have had a massive talent exodus from Rare because they've changed corporate culture and restricted their freedom to create. Had a similarly massive talent exodus from Lionhead while face-stabbing the Fable brand with a mediocre 3rd game followed by a shitty Kinect spin off.
I could go on. Suffice to say these are not the actions of someone looking to build a strong first party division. Lip service and random dollar amounts thrown at the problem on the cusp of a new generation isn't enough to bait me in. Show the love all generation long if you want to claim a commitment to first party software.
Damn, I have nothing left to say
