You have nothing but "some guy told me" so back off on demanding evidence lol. You keep making excuse after excuse "place holder textures" then the studio comes out and says they got that area of the game prettied up and ready for it's premiere shooting down that theory. You keep making s*** up based on rumors you've read and acting like it's fact, I'm using common sense. Contractors are added a lot during most game development so again this is nothing special for these studios, people who are only needed for a short period of time come in and do their work and leave.
As far as investing in big games, yeah I'm sure buying Playground and staffing up a new team to work on fable did cost a lot of money and I hope that's money well spent, same with whatever the coalition is working on next or their new Santa Monica team. You also have to figure in that they need to make most of the games they are working on right now work on two generations of consoles and 5 separate machines, the three xbox one consoles (original X1 and X1S have slightly different speeds) and the rumored 2 Xbox "Series" consoles, that is going to take extra man hours.
The vast majority of the studios they bought aren't the types of studios that are going to put out AAA blockbuster titles and if you expect that from them you are going to be disappointed, Matt Booty even said they are going to focus on high end AA content, some xbox fans try to say that was taken out of context but if you read the whole conversation that's exactly what he said.
Just because you don't like the conversation doesn't mean it's trolling, nobody is coming in here saying "xbox sucks sony rules" or any crap like that, you just keep making excuses and get mad when they aren't taken as the truth.
