I definitely reckon this has been brewing for at least a few months, as opposed to a sudden Heck decision. Dragon Rogue were claiming that the full "identity" work that they had done, including the crest, etc. would be unveiled in May. Here's an extract from an article in March with someone clearly talking to whoever was in charge of the Villa rebrand from Dragon Rogue:

You'd think Dragon Rogue would know what was happening with their own brand release, so it's safe to assume that this was definitely the plan in March. And yet none of this has come to pass and they've completely abandoned the digital identity redesign. Just so perculiar. I wonder if we'll ever get clarification on what happened between March and May, because it was clearly extremely significant.
