Considering Sci-fi is reportedly paid to keep the block on I bet that Tokyopop, FUNimation, or whoever has the rights now gave Sci-fi a fat bag of cash money to put on Rave Master.
I'm praying it's an uncut dub (though I'll say it won't be "uncut" even if it technically is, thanks to Sci-fi's annoying, unnecessary timecuts when they already murder the ERAB).
I will maintain that RM will borab horribly. E7, Macross, Escaflowne, Baccano!, whatever else has been floated, they're all better fits for the block than RM.
