Anyone noticed how all the games lately seem to be sequels?

Metroid Prime 2, Metal Gear Solid 3, Star Ocean 3, Paper Mario 2, GTA : San Andreas, Jak 3, Ratchet 3, and probably many more I can't think of...

So the question is, where's the originality gone? I mean, sure, each game has new and original advances on their previous iterations, but it's still the same idea, a similar concept, and a continuation of a name, heck, Metroid Prime 2 has IDENTICAL controls to Metroid Prime and pretty much exactly the same items, even a whole bunch of the enemies are just about the same (Grenchlers and Sheegoths for example).

Where's the new stuff, eh? =O
