According to Rock Paper Shotgun, Valve makes Hammer its next priority!

Oh hell yeah, looking forward to it.

Been practicing in the SteamVR Hammer and so far it's incredible, but very time consuming due to how slow the workflow feels, some shortcuts and mesh tools feel very inefficient - right now it's alot faster to model most things in Blender, save for the UV unwrapping and texturing.

Why the heavy downvoting on this thread though? The news websites did post their articles on April 1st, but the comment from the Valve/Campo Santo dev on Resetera is from Tuesday March 31st

Maybe check the sources before you go dumb dumb and think "hurr durr clearly april fools lololol"

I posted the Gamasutra link, because it has more references to offer than RPS, but here is the RPS article, if anyone wants to read it without clicking on the title: Half-Life: Alyx's level editor "is the team's focus now"
