Someone mentioned a "forced reset" earlier in the thread and I'm with them; I would not mind growing up as a new Glitch under the new system. Someone suggested just creating a new character but I want to keep my funpickle and a few other things; just a reset might be kind of cool based on the new UI sneak peeks!
It looks more tablet friendly, but maybe that's just my imagination. I wonder if they're considering bailing out of the Flash player implementation dead-end.
Somewhere, in some thread in the forums, it's been stated they have no plans to drop flash. It will probably be forced on them in the future, so I hope they have someone thinking about how to change it to HTML5 (and above) one day.
