While this could be a panic release to keep getting support for nothing, without any release, the game couldn't continue on if he was legit.
So while this update in itself doesn't prove BD was/is honest, and I'm pretty sure, like I said, that there won't be (m)any new renders after those 2k+ after until those are released, it is at least the potential start of returning to normal.
I myself stopped my support at the end of last month after that last poll, even though I think he has those renders and supported him during the last months although I'm pretty sure he didn't do 'new' renders beside DITLO but was in that loop of redoing stuff he already had.
And like you say, I won't start supporting him again until we see more updates and him getting back 'into the game'.
