Microsoft should be more worried about making their own stable of first parties. Taking other peoples known franchise hasnt worked for them and this gen proved it.

^{*edit2* delted the last point for obvious reasons}

Oh, this reminds me (yet again) that I need to grab a couple of THQ games off PSN sooner rather than later.

Thats great, judging by how Sony has handled the situation they've done more with less than Microsoft has done with more. Anyway, when I say stable, I am talking about known titles that Microsoft keeps because of popularity. Nintendo has a stable (with numerous system sellers), Sony has a stable (with one or two system sellers), Microsoft has a handful of games (one of them is a system seller).

They have some good stuff..like Saints Row

If Nintendo wants to do something that would look Bayonetta 2 look like peanuts in comparison buying THQ would do it

red fation and warhammer are great series. I think metro 2033 is on its way to becoming a great franchise. I like cmpany of heros too

we talking about the sales potential or the quality of the software? because if it's the quality that's based on preference but saints row for example has a lot of potential sales wise

I see. But in this situation for the buyers (I was thinking along the lines of the news in the OP) what matters is the sales potential of the IPs.

Saints row 3 did really well in sales I think ...I have heard good things about it from those who played it too. 

Ohh yeah Saints Row The Third was one of the funiest games ever
