Ignoring possible conflicts with Nintendo and integration, let's talk about cost! Nintendo, a multi million dollar company struggles with the demand because if the costs. Now this is Nintendo, a large company with money that can keep them going for 30 years making a negative profit. Now think about Playtonic, an indie bands company of a few guys, having not made a single game yet, and you expect them to come out with thousands of figures for a game? They don't have the budget. Even though it would be a hit, they just couldn't afford it.
Winners don't lose.
