I don't want it to be, it's just a feeling I have Greg's focus seems to be shifting, we generally never get updates from these guys, etc.
That being said, I'm really looking forward to Greg's Ansible EP this winter.
Moving Mountains has a new album planned for 2013, likely followed by a bunch of touring. I'm sure the success of this cycle will have more of an impact on the future than anything that's already happened. You have to remember that they just lost a band member and carried on with writing and recording which is usually a good sign of a band continuing forward (and as far as I know there was no drama that caused Nik to leave).
Your reference to the lack of updates could simply and likely coincide with the fact that has two other projects putting out two EP's, Westercheter United Football Club and Ansible, which Greg is producing both. If anything he seems musically motivated.
Buy the new Moving Mountains album, go see a show, maybe pick up a t shirt....then see if the band is back for a follow up to their 2013 release. I'm expecting them to be. So excited to hear the new album. Next update I want is a release date, and I'm sure the label will really decide that, so until then, they may not even know for sure yet.
