In anticipation of releasing Skyrim soon, there's going to be a special version of Elder Scrolls IV: Oblivion released June 28th called the "5th Anniversary Edition," which will have a $10 off coupon for Skyrim included.
Basically, I'm assuming if you have the PC version with all the add-ons, all you'll really get is a nice Steelbook case and maps of the explorable area, but if you have the consoles it may (but not necessarily) mean that they'll fix that damn vampire bug once and for all.
And if the box on Amazon is to be believed, PS3 owners rejoice...the back cover art shown there says it adds trophy support. If that is, in fact, the official artwork for the box and not some mock-up crap, that's pretty nice. If they also include Vile Lair and all the other $1.99 apiece silliness (horse armor, anyone?) that everyone else got, that might mean PS3 owners finally don't get the shaft when it comes to Oblivion. Only took 'em five years, right?

Now, if Ubisoft gets around to re-releasing Assassin's Creed for the consoles with the Director's Cut edition the PC got with all the attendant bells and whistles, we'll be in business. And yes, I'm fully aware that it's, like, 3 additional missions or something, but hey, getting to play that again for any reason would be nice.
