Hell no.
At least with physical copies I can sell them. I don't want to have a bunch of systems hooked up to my TV.
I want a smooth transition to the next generation and I want to bring my purchases, game saves, achievements/trophies, etc. with me. That they can't even give me PS1 BC is bullshit. Even the Dreamcast could emulate the PS1. That Gaikai will eventually cover every game is also BS since licensing will not allow it.
I am hoping MS will at least give us our XBLA titles, but I am not hopeful.
