I'm going to buy all the next-gen consoles. So what really matters to me is when my local shop gets the package to fulfill my pre-order. 
I will say I am disappointed that there doesn't appear to be a HD or (afaik) some flash memory around in the basic kit. Which means unless they've done something clever, require you to preload some compatibility profiles from a disc or online prior to playing Xbox1 games, or the like... the "top selling games" bit for backward compatibility is further muddied.
Though, to be fair, by the time they ship it, some of that could be baked into the Basic version. It's probably not gigs of data. As opposed to my KOTOR save games...
And Nintendo, a game as awesome and revolutionary as Mario 64 would be welcome. Especially since you're making me defer my Zelda gratification.
