Not a great deal really...
Batman: Dark Tommorow looked a whole lot better than the one that came out just before it, thought about checking it out myself.
Terminator 3 - I heard "dawn of fate" was a lot better than rise of the machines, but both look ok to me...most of the terminator games have been quite alright, so you've probably got a safe bet there....if in doubt, shop at EB.
The Riddick game, if you mean "escape from butcher bay" or whatever it was, looks really good. I've played a demo, and yeah, I liked it. As I recall, you can switch between fps and 3ps. Nice storyline that links the two films together.
Blade2...No idea, but I'd hope it was a HELL of a lot better than the (IMO) almost unplayable first game.
Run like hell looks interesting, but...that's as far as my knowledge goes.
