Good find. I'm trying so hard to find a larger image, though. I can't read the text at all, and I have really good eyesight.

It says:

This variation gives SZ the ability to create ice weapons. Armed with hammers, swords and daggers, Cryomancer is ideal for fast paced rushdown style of play

No offence, but, Icebaby found it and posted it in the Sub-Zero loading render thread, before you made this thread about it. Kudos to Icebaby.

Other than that, I just cannot wait to play Sub-Zero with this variation.
