Is Legion the most obvious xpac in WoW's history? I remember everyone and his mother could predict it.
The extra detail can be achieved simply by blending in the letters of one of the other logos. Particularly the BfA logo, which also has more saturation from the bottom up, just like this Shadowlands logo.
It really isn't difficult to make a somewhat convincing WoW logo. A 3D cg render is something else though.
I will say I think its Shadowlands because they have a writer who is clearly in to the Malazan series (Tattersail on the horde ship in BFA, the Garden of the Moon in Legion). That picture reminds me very much of the Deadhouse Gates and would explain a lot about Sylvanas as her BFA arc has a lot in common with a character in that series.
All this drama and fake leaks just adds up to the hype. Im SO ready for Blizzcon, lol
When it comes to how the story was evolving - yes.
However, I believe that finding things such as Howling Fjord textures in 2.1 files was making the next expac obvious too. Same for others that were leaked.
But yeah, I agree that without any leaks everyone was expecting Legion's theme.
