Yeah there's no good alternative Version Control right now that can handle large binaries. And for Lore from Epic Games, while it's still 2-3 years away from being suitable for Game productions to replace Perforce, there's genuine interest and excitement about using/testing it (in some cases, studios are spending tens of thousands on P4 licenses they don't really want).
