So I've watched the video review and I can't help but notice how chaotic is the new PS4 user interface. I am not really a fan of the current PS3 store design, it looks like they have taken the same approach to the overall UI on PS4.
By the way, are there good developer-level reviews of the hardware? I'm not a console developer (sadly), but it would be interesting to get a little insight about what's it like working for PS4 or the XBone.
