There's a Sony store pretty close to me, and it's on the list...def gonna check this out.
I visited the SonyStyle store at the Stanford Shopping Center this afternoon. They have four (!!) systems running. Three are on 55" LED screens, and have (wired) controllers available for hands-on use. Another unit was running in a demo loop, connected to their 4K demo display (excuse my drool)...but no controller out in front.
The three hands-on setups had dummy PS4 enclosures out to look at; I was initially shocked when I picked one up and it felt so very light!! They swore to me that there are real PS4's inside the pedestals, and not PCs; who knows for sure? The dummy units were odd; for some reason there is a mini-USB port inside the cutout for digital optical audio out! And nothing in other ports, such as HDMI, LAN and Eye. Weird!
The demo SW is pretty basic; it does NOT allow you to see the XMB menus at all. There are playable demos for about six games. I tried several. Knack seemed quite polished whereas Octodad (sp?) looked more like a PS2 game in its visual refinement! There was lots of information about a jillion other games, for PS4, PS3 and Vita, but these had no demo, just screen shots and trailers.
I liked the feel of the controller with real games, for example Pinball Arcade. ("Circus Voltaire" is the playable demo). On this and the other demos the help screens for "Controls" all showed the updated controller layout.
Whenever you quit from a demo game (not the screenshots or trailers) it seemed as if the entire system rebooted, reloading EVERYTHING from scratch. It took a while! Similarly, when there were loading screens starting or within demos, they did not feel any snappier than on a PS3.
Despite a few disappointments (it is just a prerelease demo after all!) I am psyched and looking forward to my launch day console arriving!
