I actually kind of prefer this gen (PS Wii60) to the last (GC,XBOX,PS2). There has been a resurgence on sorts for 2d gaming and getting more bang for your buck. ($1 indy games much?)
That's the good thing that has happened, but the bad outweigh this, in my opinion of course, and includes but not limited to always online DRM, extreme patching and heaps of DLC, profiles which needs to be signed in, hacking issues, CoD wannabees and headset equipped online-twats, Activision, Zynga, EA, Capcom, large scale system failures for two out of three consoles, "westernisation" of Japanese franchises and the cancellation of Mega Man Legends 3
Also dubstep

Edit:
At least the PS3 & PSP is region free, a decision that probably took more balls than I have and something I applaud.
