Will there be a portal 3

Nothing has been announced as of May 22, 2011. But there is still one unfinished story chell's past I don't know if there is going to be a portal 3 but I sure hope so :)




SPOILERS!!!

I hope there is, but Chell's life ended nicely, her leaving. If valve really wanted a portal 3, the field chell went to could be fake, a test chamber...

Then there is ratman, Atlas and P-body, and at the end of the co-op coarse, there were alll thoes test subjects..

Please valve!!! PORTAL 3
