Yeah it's true Ubi and Epic are not the companies I'm worrying about as far as pc games go. It's just that they may be starting a trend, and if that were to happen to say Bethesda? That would be a shame because I will not buy Bethesda games on the console.
As I said before - where there is a free market, there is competition. You can be sure that:
1. A company that has built its position on PC games won't abandon it's profits;
2. ...And if they are somehow stupid enough and did, there are plenty of other developers, just waiting for the chance to take back at least a small part of the market.
A company either makes good games and has profit, or it's making crappy software, alienates its customers, loses profit and market share (and is being eaten alive by people who actually do what the gamers expect).
Apart from that, after what Bethesda did to Oblivion I wouldn't be a tiniest bit sorry if they decided to go away.
