I mean, I have a 4K TV and need a 4K Blu-Ray Player to get the most out of it anyway. I pre-ordered the 4K disc for Deadpool with intent of watching it in 4K one day, so I'm not 100% against the Neo. If anything, I'm pissed the original PS4 will bottleneck the (Dr.) Neo (Cortex... Crash 4K confirmed).
However, I want to see developers be able to take advantage of the Neo's full capabilities, if possible. If that meant using the extra memory to increase a multiplayer mode from 2P split-screen to 4P split-screen, I'd be happy to have those extra kickbacks. I get that this is to make it not be a PS5, but at the same time, Sony could have waited one or two more years to make the PS5.
