The 3DS has sold north of 54million units worldwide since it released in 2011. Though it's not the numbers the DS put up during it's time on the market, it is still a substantial amount.
I don't think we've seen the end of handheld gaming. Not by a long shot.
Money talks. Games like Titanfall and Rise of the Tomb Raider may not have happened without the aid of Microsoft. Kojima needs a company with money to bankroll his projects and it sounds like Sony made a very convincing argument.
Publishers are probably put off by Kojima due to his production budgets and schedules, but Sony wants to continue to convince players to play on PlayStation.
I wouldn't recommend the 2DS to a friend under normal circumstances, but if price is prohibiting you from buying an system with an incredible library of games to play, the $99 2DS with packed in Mario Kart 7 is a steal.
The included video makes some decent points about whether we'll see price drops on other models and if North America should expect to see the New 3DS sometime soon.
Though the Wii U has never really grabbed hold, I don't think Wii Street U had any power of the purchasing decision of its customers. Really a silly thought, but hey, hopefully the NX brings them back on track. Right...? Right!
