So...it's just better graphics? Same catalogue? Why would I? My PS4 does quite well on its own, thanks.
I don't disagree with this sentiment.
But for what seems the majority, the PS4 version of the multiplats being just "better graphics" is enough reason. So, my guess is that if this is true, the graphics whores who count the pixels while running and gunning or racing will clearly need this upgrade.
True but it won't look much better than it does. It'll just be 4K at best. Probably better processing speed. When you make something like this you're confining the product to a specific and limited market. People who will buy another PS4 for the sake of pixels and slightly enhanced processing power and those who are just okay with their current experience with PS4 that don't want to drop another 300-400 bucks on a slight upgrade. The latter will be much greater as long as the catalogue is the same.
3DS is huge. Not as big as DS but it's 60 Million units sold. The New 3DS came out to some fanfare but after a while it died down and only has a few games exclusive to it. But now the New 3DS is the model to buy while phasing out the older models. If they go with this "New PS4" idea. It should gradually phase out the older models because the newer one will be the one to buy just like the New 3DS is the console to buy for the 3DS family. I guess Sony is just trying to reach people who will pay for a premium experience because those people do exist. It's just going to be very limited unless the old PS4 is slowly phased out.
