New listings from the ESRB reveals that RBI Baseball may be on deck for an Xbox Live Arcade remake. According to the listing, RBI Baseball is to be published by Six Degrees Games, but the developer makes no mention of the game on its official web site, nor has the game been announced as an XBLA candidate.
The original RBI Baseball, for those who aren't familiar with the title, was published for the NES by Tengen and was based on the Famicom baseball sim Pro Yakyuu Family Stadium. Sounds almost perfect for casual online multiplayer baseball fun, no?
