The hope was obviously that EGS would be good for smaller games. On the most part it seems not to be.
I reckon we'll see more talk like Devolver, about "resetting" the discussion on Steam's cut, because Valve has clearly not given in to the pressure and some developers/publishers of smaller games clearly want to try and rebuild bridges.
Basically, from an indie perspective, the gambit to force Steam into a better revenue split has failed. At this point anyone going to EGS knows their game will sell like shit, but they're doing it for the guaranteed cash. The jury is still out on mid-tier and AAA games, however. I think if the poor sales tail impacts the bottom line then Epic will have to fork over more cash for AAA exclusives or make the exclusivity window shorter.
