Monster Manual 3: What do we know about it?

And on a tangent, sapphire dragons are awesome, and I had a grand time with one of them in my last campaign.

Well I'm glad you find sapphires awesome. BTW, did you use it with my suggested psionic update (shameless plug)? And no, the link in my sig is now broken. Migrating to Webring and made a wiki entry at Wizards.
