He's showed up to debunk what needs to be debunked and help out where he can.
Other than that, if there isn't something that needs saying, there is no need to say anything.
He likely still checks things out on twoism here and there, looking for anything that needs the attention of an official statement. It's happened before that he was very quiet for a long time and then came out of the batcave to clear something up that needed clearing up.
Most of the conversations here in the last while have just been speculation and odds and ends. Being a friend of the band, he much more than likely has no need to speculate at all. If there is something solid to say or show, it'll likely start through an official source like WARP Records. If there is nothing solid to reveal for the time being, what is there to say that hasn't already been said? They are working on stuff.
No worries about this thread. It's a valid question that I'm sure many more than just yourself are wondering.
Welcome, by the way.
