Hardly, PS3 cross bar has 4 directions of movement, we're using a carousel with only 2 directions. I can see how it could be confused with ps3 having a dark background and white icons, but its hardly PS3 influenced, I don't own a PS3, never will and think they're interface is too simple and plain.
Isnt that the whole point of the xmb. simple. I own both, the PS3 xmb is way better than the nxe dashboard. The xne from my point of view looks like its trying to get you to spend money all the time. There are menus everywhere that connect you the marketplace. The older dash was way better. A side scroling friends list is just plain stupid. whats wrong with a list? The PS3 xmb is just way easier to use. And it isnt locked down like the xne dashboard, has video previews on the xmb, and the list could go on. IM NOT A FANBOY as I own both consoles. Just find the PS3 xmb a lot better.
