5+ was probably too many to support by most game devs, but 3 would be nice and solid. It's also nice that we'll have another player besides AMD that actually gives a shit about Linux/OSS drivers. nVidia might finally be forced to open up and contribute to Nouveau and bring it up to par with amdgpu. The future could be a team green, team red and team blue. Intel has killed the discrete graphics projects before though. So we'll have to wait and see.
