This week Disney Interactive responded to rumors by posting on their official website that the Disney Infinity franchise will end and that Avalanche Studio will be closing. Disney Infinity 3.0 will get a short remaining lifespan as three Alice Through The Looking Glass figures will release in May 2016 and the Finding Dory playset with Dory and Nemo will land in stores in June 2016.
