Console support is always a good thing for the developers (of the game and the engine as well), the console provider company and the players. It's an all-win situation. Construct 2 is one of the best engines in the market and it deserves much more attention. Complex and big games can be made with it and having those games on the Xbox platform would benefit all parties.
As for my personal perspective: We've just started to create a bigger game and our plans included Xbox from the beginning to publish it for. The most wanted feautre for me is the achievements.
