Make it happen Valve... make it happen...

What in the nine hells...?

I know about this. Since the update from 20th april there are many posts on the Steam forums making analogies to World of Warcraft ("lvl 48 medic LFG group for cp_gravelpit raid to find epic bonesaw" and such). I will personally wait for next patch(es) to find what is it all about. Until then I won't judge it.

Haha!
That would be hilarious - probably not as fun as my imagination makes it out to be - but hilarious nontheless to see.
After all, ever since I got The Sandman I've been looking for an equivalent epic item to make my balls go more "Boink!" ( ! )

It's been dubbed World of Team Fortress (WTF for short).
All anyone really knows for sure is that there well be hats (the Demoman gets a 'fro), and that there's code for weapons with arbitrary statistics.
A recent update gave us a 50-slot backpack (with a permanent delete button) making many wonder just what it's going to be full of.
Until Valve saying something official, we're all just basically guessing, and having fun with Gmod and Photoshop.
