Just preordered Counter Strike Global Offensive for $11.99 since I am a Playstation + subscriber.
I was going to do so regardless, but one bullet point really, really stood out to me as I confirmed my purchase...
Developing for PlayStation 3 gave us a great opportunity to take advantage of the unique qualities of the platform. For example, we’re supporting a wide range of input devices including the PlayStation Move, PlayStation Move sharp shooter, and even keyboard and mouse.
The part I bolded. YES. My wireless keyboard and mouse Logitech combo I purchased specifically for Unreal Tournament 4 way back when for my PS3 is finally making a comeback. So very pysched.
Now yes, obviously this is a PC gaming franchise, and as such should be played on the PC. But I make no qualms admitting that these days I prefer gaming on my couch on my 55" TV. After working in front of a computer all day, the last thing I feel like doing is sitting in front of my PC when I get home. So yeah, even though me using a keyboard and mouse begs the question, "then why not just play it on the PC," again I would answer because I like my TV and my couch.
What is even better is this snippet...
Naturally, support for these devices means that different players in the same match might be using different controllers. Players using mouse and keyboard might end up playing against players using a joystick or motion controls. Our matchmaking system allows us to support all of these input devices without disrupting the balance of the game – you’ll be matched against players who perform at your skill level, regardless of what controller you (or they) choose to use. The system maintains a separate ranking for each input device, so players should feel free to experiment with each one.
Hell, after reading that, I am even going to dust off the old Move peripherals and see what that is all about as well.
Actually pretty damn excited to have CS coming to the consoles. A few years ago I would have literally said what a terrible, terrible idea, but I now have a much more open mind.
The above two quotes, and the rest of the article, can be found
on the Playstation Blog.

And actually, I will probably also wind up purchasing the PC version as well. But going to hold off on doing so after checking out the PS3 version.
