While everyone's focused on the next round of standalone consoles, I'm already looking forward to the future of handhelds. Oh, sure, we've got Nintendo's 3DS and the PlayStation Vita already fresh on the scene, but it's not so much a new, portable platform to which I'm look forward. In fact, the basic concept is one that's rooted in handheld games of past, could probably be cobbled together with the technology of the present, but would probably have to wait until the future anyway, given the relationship with staying current held by the company that would have to make it.
Your move, Nintendo. Call me, maybe?
