I have a PS4, and have barely touched it. I am getting FFXIV for it in a few days (preordered) so that will change, but I admit that most visuals I've seen hasn't blown me away. I admit I haven't gotten Infamous:SS or MGS:GZ (I'll wait for them to hit PS+), but Killzone, as good as it looked, just didn't wow me like I expected. I don't know much on the tech side of this, but even if PS4 smashes Wii-U spec-wise, visually, I have yet to witness that power gap being as great as so many profess it to be.
Surprisingly, I've been impressed with some Nintendo's offerings, most notably Mario Kart, Mario Land 3d, and X. If people want to chalk it up to art direction, I don't see how that makes it some caveat that should make people disregard the prowess of Nintendo's system. It still takes some muscle to allow the developers to adequately express their artistic merits. Wii-U has that muscle and should not be taken for granted because what their top games are capable of won't be seen on a lastgen console. PS3/360 just doesn't have the chops to do what is shown in the 3 games above (or even SSB Wii-U, because it blows Playstation All-Stars, both visually and gameplay-wise, out of the proverbial water).
OT, MK looks better than most of what is offered on "nextgen" systems, and destroys any cart racer on PS3/360. The tech in the Wii-U can't be that bad if it can impress like this in the midst of newer systems coming out. I'd wager to say the difference between a Wii-U and PS4/XB1 is more like PS2 to XBOX/GC than Wii to PS3/PS4, because no matter what the raw numbers are, the Wii-U's best is still visually competitive to whatever is on PS4/XB1.
