I haven't perused the entirety of the RBN request thread lately, but I'm more than sure this band has been mentioned in there. If not I know there's been requests for the band in general outside of RBN for a while now.
Rest assured we're just as eager to announce this as you are to hear it. And hopefully things will be signed and dotted by Friday. If not as soon as they are you'll see a post and know about it from the fireworks shooting out of my butt :P
Seriously though this was one of my top five I want to get this band's material into the game (and let's not be silly and think this is a band like Metallica or some insanely huge popular band).
The only hints I can offer are that they are a metal act (doesn't mean that we don't have some pretty cool non metal stuff to announce Friday as well), and while they're aren't mega huge/known across the world they are known and have a decent fan following.
So look for the fireworks in the sky as your first clue :P
