Why are devs actually grumbling? Does someone not get paid for the extra work? I know that if my bosses wanted extra reports run I wouldn't be happy about it but I would suck it up and do my fucking job. The only people who should be grumbling about this are the people who are paying for the hours to implement it. They should only be grumbling if it is going to be a net loss. Indy devs is the only case where I see someone possibly getting fucked over on this. I am sure Sony can offer some support in these cases.
This site is very pro dev and while that can great, it also evokes some of the response this topic has received. Fear mongering for our poor indentured devs. If anything this should create jobs for people with the implementation and testing.
I remain skeptical about just how much work a different performance profile is going to be. For most multi-plats the game has to scale to PC so it isn't going to require new asset creation or any truely expensive work.
It's almost always unpaid and just totally expected for you to just do an 80 hour week when it comes to the crunch. I could easily see developers at most levels not liking this as it will mean more crunch and for the people managing the budgets, possibly more resource if the people you already have have literally nothing left to give.
But they'll only hire the bare minimum of people working another 80 hour week as temps to get through the extra NEO version or whatever, so more money spent and the existing crew still has to pull the same amount of shit.
