I think he's rolling to the right.
I do think there will be blocking, because of the two images of Link, and the image of Ike, in that blocking stance. And in the Ike pic you even see the little light that appears when you block.
But in Melee if you powershield doesn't that not even bring up your shield? And if so does that mean they could have just been powershielding?
On second thought, the pictures of Link don't have the light to signify that he powershielded, and his opponents weren't making contact, so unless Link and Ike both have counter moves, I think there is definitely guarding in Brawl.
