Speculating with how long it took to jailbreak the iPad 2, it might take a while. I always noticed jailbreaks being mainly exclusive to the older iOS devices but almost never for the iPad2 itself beyond firmware version 4.3.3 using jailbreakme.com. After that if you were unlucky not to have the shsh blobs saved that was the only chance you had before the next firmware updates plugged the hole allowing the jailbreak. I compare this against the iPhone 4S because the main thing that stopped jailbreaks for the iPad2 was the change over to the A5 chip, which both devices now share. Also doesn't that Comex guy work at Apple now? Hm..
Edit: I am aware that jailbreaks do exist for the current iOS5 but from what I'm seeing, they are tethered and to further emphasize.. don't work on the iPad2 either.
