I got my 2 moves and a navi from the UK yesterday (suck it, Japan delay). Build quality is excellent and sits very comfortably in the hand. I have quite big hands so I don't have to adjust my grip at all to press all 5 buttons, it's very nice. The trigger is a real trigger, holy shit why can't they DS3 have this? Navi is what you'd expect, again comfortable to hold but I notice the the trigger on the navi, while concave, is squishy like the DS3. Don't know why they don't just put the same sort of trigger in both.
I have Heavy Rain and RE5 Gold, and I really can't be bothered to play HR again, let alone download the giant patch so I've just played RE5 for now. Works very well, the cursor lag is low enough that I would consider it negligible. I admit though I'm having a hard time getting used to the button layout. I really expect the knife to be on L2, not L1. Move button should be aim and trigger should be shoot. Plus interaction buttons can be a bit weird. Picking up items and opening doors is bound to the move button, but stuff like assist jump is circle, with move button to cancel. The cursor seemed to move far too fast on the default 5 setting, but once I had it down to 2 it seemed ideal, my accuracy went way up. IGN did make a fair point though, it's a bit of a pain you have to go into aim mode to look around. I don't know why you can just the move to adjust the camera when not in aim mode, since it's not doing anything else.
Also had a quick go on the Echochrome 2 demo, what a pile of shit that was.
Only slight quirk I had with move in generally was I went to try out the web browser with it (it's shit) and after I'd finished I could no longer navigate the XMB with gestures (though the turn off controller/shutdown menu worked fine). Had to reboot to get it back again. I'm just going to blame the browser for that.
Anyway, very impressed with the hardware, even if the current software implementations are a little lacking.
