In my view, the PS4 has potential, some of the online features sound amazing, others are just horseshit that could ruin gaming.
Graphically, it's a nice step up, but my PC and laptop can do better and they aren't even top-range, and that's disappointing.
I will undoubtedly get one, but not at launch and definitely not at the rumoured price.
Nintendo don't have too much to worry about here. Their innovations are still key. Miiverse, although it lacks the video stuff, still trounces the Sony network we've seen here.
The Remote Play is ridiculous since you need to buy an expensive extra console to do it, rather than one packed in.
The problem here is that the majority of the games are third party and will be on other devices, INCLUDING Wii U and past gen consoles. As such, there's very little enticing to me at this time, and I hope that changes.
