Any system that could pull off a AAA, universally praised MMOFPS/adventure title with team play, competitive play and RPG aspect (leveling, stats building, upgrading) that is extremely easy to pick up and play for quick sessions but also deeply engrossing for those that want to delve deeper into a story mode would be a day 1 purchase for me. I'd also want social networking integration/iOS/android apps so that you're connected to the game world even when you aren't playing. Not intrusive, annoying crap but alerts about up coming battles or wars in your region or maybe options in micromanaging certain aspects of your character etc
Apart from that..
Wii U: have to have an online multiplayer heavy game from Retro Studios and a Mario title on day one.
PS4/720: Would have to be home to the above dream title.
