No, the break even point would be 2/3 but since the PS4 version likely did significantly more than just break even than the Switch version would not need to sell 2/3 as much as PS4.

I think you're both wrong, its certainly not going to "sell like hotcakes" but it should do fine for what it is.

And why would you go just for break even?

Besides ROI there is cost of opportunity. If the game port cost close to another version but sell much lower that isn't good at all.

PS4 version done 2.66M, X1 done less than 1M, do you think Switch will do 1.8M or will the margin of the investment on the PS4 port be much higher?

Nothing i said implies they are going for just breaking even, i said the break even point would be 2/3 of PS4 and since the PS4 version did significantly more than just break even, it does not need to sell 2/3 as much to be profitable.

I absolutely do not think the Switch version will sell 1.8 million or be as profitable as the PS4 version and i highly doubt Blizzard expects that either.

Damn it takes almost a year  for 2 consoles at the same time and 2 consoles that is different and exotic to program. That super fast

It will easily sell over 1m copies. I'm willing to bet on that, too.

You're generalising though. Sure, there are some Nintendo / Switch fans that might actually say and think like that, but that's far from the norm. Besides, your original words "Yes, so much for how easy is to port for Switch, most friendly platform ever and that devs not doing it are morons", are borderline flaming, if not at least provocative.

Why is this even a discussion? Don't people here know how long porting a game takes? 9 months with 8-9 core staff is a reasonable amount of time - short even. It implies a porting budget of aprox half to 1 million USD. Including marketing, overall costs could increase further, but this is par for the course for a port really. Do people think you throw in your code, re-compile it and voila?

People are seriously lacking understanding of the process and costs of game development.

Depends on what you mean by well. Skyrim has sold close to 1 million...and lets not forget the 4 year old port of Mario Kart 8.

Maybe it's not super fast if you have most of Blizzard working on those ports, also it those ports could be in development even before PS3/360 version were out, and when we talking about PS4/XB1 we talking about very similar platforms and hardware.
