Some new footage about Portal 2 was shown in a non-playable trailer at GamesCom:

There also appears to be a new voice actor for Wheatley, British voiceactor Stephen Merchant.

awesome new footage! i just wait till it comes it comes out ( it would be funny if it came out JAN 1st, so valve would keep their promise, but almost keep their old one! )

aaah, dynamic lighting... almost feels like Doom 3 finally

Cool.

It's not going to be coming out until mid-2011-ish.

Umm. Strange error where SL89's post appears on the homepage?
EDIT: replacing the news post!?!?!

Weird that it's never happened before, but not surprising. The homepageh here is running on a very old version of some code of mine, long since been cleaned up drastically (and in use over at F7).

Anyway, it's fixed.

Bump for higher quality 720p version.

Look Closely at the water at 7:42.
