Will we see Warwick next week?

Nothing confirmed yet, but very, very likely :)

Dunno, nut there's always a chance.

Probably a very high chance given the teaser.

No guarantees, but a good chance none the less.

Well they know that if they hype things up too soon,the hype will be gone on the release day,so it is very likely that we'll see warwick in the next pbe-cycle,which will likely arrive next week(most stuff thats currently on the pbe seems to be finished by now).

Likely, the PBE ends next week, so we will probably see him around Tuesday

I think so, I'd expect it on like Wednesday or sooner.
