So they'll release a 15" version of the 12" soon enough. The point still stands: if Apple is the only ones making Macs, they need to cater to those who would prefer workstations or gaming rigs as the highest end "Pro" market. If it needs a separate graphics card, it's not for Excel...
I think the ship on gaming macs has sailed. Apple has shown intermittent interest in high end computing, rendering, compilation and so. But the only "gaming" machine they ever produced is the iPad. None of their PCs was even remotely competitive with the competition and I believe they do not care.
I think that the only thing that could "trick" them into making a gaming machine is VR, as it requires similar hardware.
They made their brand exactly by caring about the people they are throwing away now. It's not obvious if their brand will sustain itself without those people.
