To those irked that the Pro didn't up the specs or whatever, think of it this way: Developers will continue to be forced to make games with decent frame rates for the PS4s most of us already own, regardless of whatever pricy shit Microsoft and Microsoft pull, because this is where the bulk of their audience is.
I was thinking about this while I was seeing the negative reactions people were having. The PS4 Pro at $399 is not compelling when compared to the $399-$499 Scorpio that's coming next year. However, the Pro probably isn't going to be $399 when the Scorpio comes out, and Microsoft has already said they're not mandating developers make their Scorpio games run on Xbox One. I think Sony is playing the timing game. If Sony's goal is to transition people from new console to new console without them losing the games they already own, then is the Scorpio really that appealing? Is it more powerful? Yes. Will it do more? Probably. If I own 50+ PS4 games am I going to get one? Probably not. I'm probably going to either get the Pro (doubtful) or just wait for the more powerful PS5 to come out in 2018-2019.
While I have no desire to get a Pro, I do think there are some really silly reasons that people are getting irked; not the least of which is the "no one owns 4K" idea. Nintendo wasn't exactly lauded for taking the same position with the Wii.
