I would say it has heavily influenced this generation. Here are the most significant ways:
1) The ease of development between the Xbox 360 and PC lead to multi-platform games being the standard in the West and increasingly so in the East as well.
2) It has heavily influenced online console gaming (Xbox Live Arcade, DLC, movies, friends lists, achievements, etc).
3) It lead the way with multiple SKUs that offer varying levels of hardware configurations.
Those are things off the top of my head but I'm sure it's also responsible for bringing so many FPS games to consoles (any third-party that makes them seems to always bring up the Xbox 360). Or the fact that we're seeing more and more multi-platform JRPG console games.
