That's calm speculation! I was asking for wild speculation.
DOTA2 was a elaborate hoax, it was really just a test for MvM mode.
Weapons won't have stats in the new mode, everything will be based off your hat. Different hat combinations unlock new classes & playstyles.
Secret sources say that they're working on a Hoodoo re-make, but it's been delayed a lot since they basically have to start from scratch to make it a decent map.
A hidden hex-code in some of the MvM files point towards the *next* official game-mode being Pipeball.
