It's funny looking at the upcoming big releases and how they're engineered to bring people into the next generation of consoles.

Legend of Heroes: Trails in the Sky: If you want to find out how the story ends, you have to buy a Vita.
Halo: We're starting a new story but, if you want to finish the fight, you have to get an Xbox 720
Soul Calibur: A new chapter begins and the first game is the introduction to the story which will continue on the next generation.
Resident Evil 6. 5 finally wrapped up the ongoing story that started way back in 1998. But you remember that note about the Wesker clones? Come along with us for what may be another decade-long story spanning 1-2 consoles generations.

It's interesting how what started with the Playstation 1 (and my friends can tell you how irritated I was when they pulled this stunt with Soul Reaver) has become an accepted industry practice which keeps gamers chained to a never-ending cycle of consumerism.
