The re-released game with all previous DLC included, sometimes known as "GotY Edition" or simply "Platinum Hits," "Greatest Hits," etc. is now relatively common. Nowadays, it is not only on PC, where re-releases and compilations have been common for much longer than that, but also on consoles. 
 
When looking at discussion (particularly at CAG) for big RPG-ish games that have numerous DLC releases planned, such as Borderlands, Dragon Age, and Mass Effect 2, there are a few people predicting (or sometimes outright stating) that there will be a GotY Edition with all of the previous DLC, and they will wait until that edition releases to buy the game. In the case of Dragon Age and ME2, I went ahead and bought the game anyway. 
 
With Borderlands, I hesitated -- and continue to hesitate -- despite the complete lack of official news on any re-release edition.  Now Amazon is offering Borderlands and the first two DLC for $40, and if Gearbox only releases one more expansion at $10, then I could get Borderlands and all its DLC now, for effectively the same price as a $60 DLC Edition.
On the one hand, sales are bound to slow, and companies will see an opportunity to possibly get sales from penny-pinching consumers who have previously been afraid to take the plunge and buy their game. On the other hand, not every company is Bethesda or Blizzard; not every company is so quick to compile their games and expansions at an improved value.
 
What do you think? Will we see "GotY Edition" re-releases of Borderlands, DA:O, and ME2? Will we see more of these re-releases in general?
