Nobody knows for sure. Elbox say that it (OS4) will "just work" due to high compatibility between SharkPPC and A1. Hyperion say it won't work, and they can't make it work because Elbox havent supplied them a SharkPPC.
It's a tough call who to believe since Elbox certainly know their stuff and make some pretty #### hot hardware but then again they could just be using the OS4 compatibility line to sell more Mediators as people like to think they're future-proofed.
