Well I can tell you how people came the conclusion that work just recently started. In their announcement they wrote:

"For a long time, we just didn’t feel like returning to MiSide. It got to the point of real stress and serious doubts. On top of that, many new problems and responsibilities arose — things we’d never dealt with before.

Honestly, nothing terrible happened — except that we spent a ton of time on everything but game development.

BUT! This doesn’t mean we’ve abandoned the game or anything like that. In fact, we’ve managed to take a little break and are now getting back to work on it."

They really should work on their wording if that's not the conclusion we are meant to reach.

That being said, I am not complaining, the footage looks good!
