Song of Ice and fire 3 "season of Storms" is announced for June 17th at amazon UK.
The American edition seems to need a few additional months though.
It will be out as Hardcover and paperback simultaniously.

So what are you thoughts/theroies:

Personally i would say SoIaF is my current favorite even before the Lifeship traders.

Martin especially shows Robert Jordan how to do it right, in my opinion. DON'T REPEAT yourself.

He also shows the ability to keep the number of characters manageable by killing off some all the time, that keeps the tension high too.

All in all: If you read it bring your opinion.

If not get the first two volumes "Game of thrones" and "clash of kings" now, you will be ready for volume 3 (of 6) in time.
