Xbox one, the US initial boost will be big but 6 months later I think the ps4 should be outselling it regularly

PS4 easilly, assuming Sony doesn't makes the same mistakes MS is this gen with the ridiculous DRM stuff..

I would say PS4, but it's possible that the PS3 will still be going strongly enough to take some sales away from it, especially with GT6 launching this Holiday.

PS4

Not sure what side to take till E3...but for now If Xbox Live for Xbox One Isw anywhere as good as it was for Xbox and Xbox 360...MS has a high chance of taking it this year...Though PS3 has solid performance behind it's belt and scare of failling hardware might down play MS...But really till E3 it's in the air IMO

I'm inclined to say PS4. It won't break records as some are expecting, but as of now, it looks more tempting to customers than X1.

Can't tell right now but I'll say the PS4 just because gamers aren't very happy with the Xbox One and PS4 has a advantage in Japan and Europe. However, if MS can fix this mess and improve the image of their console as well as have a great E3 with lots of great exclusives, then I'll say Xbox One.

Same price, same launch day (same amount of game and exclusives): PS4. Unless MS brings out something amazing at e3.

Ps4 because ps3 out after xbox360 and was way more expensive and xbox360 stole biggest third party from Playstation but ps3 still outsell xbox360.
This generation it seem all this threes big advantages will not happen to microsoft so ps4 should outsell it.

How ps2 do compared to xbox and xbox360 in USA ?
