you might be in for a long wait if you go through Right Stuf, or possibly anyone else, for the Bandai stuff. i ordered Jin-Roh on BRD back in Nov from RSI and didn't recieve it until sometime Feb/this month. it was in-stock at the time but also part of a sale so i figured it ended up backordered due to high demand.
it's most likely a distribution problem on Bandai's end though. places that list their BRD's have them listed as backordered/on-order from manufacturer and it's been that way for quite a while.
