So it's similar to Defence of the Ancients that resulted in DotA and other MOBAs. It wonder if they'll be able to create a version of this with the new mechanics/gameplay loop but with different art/assets.

There's 3 scenarios they could follow:

1) Create a new IP with the knowledge they have from Turtle WoW, create a similar game and market it 2) Contact Blizzard, apologise and maybe be brought into the team to develop updates for Classic or Retail 3) Drop the whole thing, leave the project and disappear

Would be great to see #1, but I'm more expecting #3

Yeah, that seems like the logical next step here.
