I got mine from Amazon so no idea about in store situations. I can only note that Move has steadily climbed amazon top sellers in UK until I think it hit number 2 behind Reach (for the bundle).
So far so fun - Sports Champions seems decent and I'm just working my way through the various demos with my kids. Tumble seems very good from the demo. Seems very responsive and it's interesting to rotate the Move in your hand and see your racquet or whatever rotate right with it.
I got a sub-controller but haven't had to actually use it yet so no idea how it feels to use.
You order from amazon UK? I pre-ordered from there and it didn't ship until yesterday, I didn't get it today and may even need wait unti Monday.
I hate pre-orders from them, I always get stuff late, if this was game.co.uk I would have got it Tuesday-Thurs before release like all pre-orders.
Amazon was cheaper though by a notable amount.
I don't normally order from them, but when I decided to pre-order they were cheaper and as I was ordering 2 Move's plus a sub I felt the extra savings was worth it.
There delivery policy must be weird though as they delivered the stuff seperately, first the Move's arrived, then the sub-controller 4 hours later. Strange.
I actually rarely pre-order stuff, I tend to pick up games after launch as I'm the patient type and like to see the real reaction to the title first.
