Yeah I was kind of 'meh' about this year's, I just thought it was too soon for another full installment and respected Harmonix for holding off on RB3 in order to innovate. But then I found out about importing in GH5, in the Wii version too (the one I play), and got more excited. And then there's the fact that, despite Activision being a horrid company, Vicarious Visions are a brilliant developer and have somehow managed to bend the rules and create a seamless, HD-aping 'always on' online enviroment, DS connectivity, background downloading, no Friend Codes, the ability to buy track packs and most of all, the ability to choose which songs are imported (so that's a no thanks to 'Good God - Anouk' from WT).
And to top it all off there's the new modes, like eliminator, and that one which changes difficulties depending how you're doing. I must say, they both sound rather good.
