so every system has it's flaws, including the new 8th gen systems, so if you could change one thing about the shiny new next gen systems (3DS, Vita, WiiU, Xbox One, PS4), what would it be? and for what reason(s)?

for me, it'd be like this:

Xbox One - remove the Kinect from the bundle (obvoius why).

PS4 - keep online multiplayer free (i ain't paying for that shit).

WiiU - add more ram (I've looked over the specs and honestly that's the only thing that could hold it back IMO).

Vita - give it games (the thing hasn't had a good release over here for a long, long time, atleast Nintendo is trying to turn the WiiU around -.-)

3DS - give it a 480p screen (for the size of the 3DS's screens, it would only cost about 2 fucking dollars, i heard that the 3DS is more powerful than the Wii, and having low res screens can REALLY hold it back).

what about you guys?

I would change 3DS's screen. Resolution is fine, but I've been spoiled by my phone's OLED screen and the awesome contrast and black levels it has. C'mon Nintendo, OLED's are not cheap, but do this in a next revision!
Also, I would want MS to go back in time to never say they were trying to impose always-online and abusive DRM policies on the Xbox One. It has the exclusives I want, but after what MS did I simply won't buy the console, at least not until it's sucessor is released.

About the other consoles, everything seems fine.
