Got my move, some quick impressions:
Echochrome: nice enough use of the pointer as a torch, but I never really got on with the first one, was a little too abstract for me much beyond the tutorial levels, so I won't buy the full game. Nothing spectacular in terms of motion tracking etc
Beat Sketcher: No idea what the point of this is, other than doodling on a video image of you. Got annoyed quite quickly as the tracking seemed to be literally the position of the move ball. So you had to move the controller really far to get to the extremes of the screen (start the party had a little of this).
Sports Champions: Only one hole of disc golf which was disappointing. Controls were quite nice but the demo wasn't long enough to get a real feel for it. Oddly it says to stand with your leading shoulder towards the screen, but then if you reach back for a full throw it loses sight of the Move and complains. You'd have thought they'd have noticed that, and could probably have relied on the gyro/accelerometers anyway.
Table tennis was surprisingly fun, and some nice 1:1 after serving. Probably not my cup of tea though. May pick the game up when its a little cheaper, as I'm curious about the archery.
Start the party: Got the full game of this and its a little meh. Worth it from my tech-geek perspective to see how it maps the game's items to your move on the video feed, which was really impressive. Quite liked the fan & helicopter levels, the twisting is nicely tracked. Not so keen on the fish popping level, wasn't sure how well it was tracking my depth, but that might be as I was too far away, it complained a few times. Will experiment. Overall it'll probably be a fun distraction for the kids, but I'll want something that offers more.
The Shoot: Really enjoyed this, probably the surprise hit of the demos for me as I wasn't expecting much. The tracking was fast and seemed accurate, although I did notice it losing tracking on the train level. After pumping the move up and down to propel your wagon, when I pointed back to the screen the cursor tended to be off to the left a little.
Overall though it was a nice first feel for a lightgun type game. I'll try and pick up a gun shell at the weekend to see if that improves the feel even more. Will probably pick the full game up, depending how close to Time Crisis its released.
Eyepet: Had a major problem trying to calibrate where the floor was. Did it in the end but the 'floor' ended up in the middle of the air somewhere. Also we had to point the camera down more than with the other games which was a bit fiddly. The augmented reality is 1000x better with the move than with the card and actually makes the game a relative pleasure to play. This also has 3D support but I'll probably not use it again, especially as my younger kids play it - it isn't particularly effective or add anything to the game.
Tumble: Fantastic. Looks great, the controls offer real finesse, and the stereoscopic 3D is effective. Playing through the tutorial it was second nature to put the blocks through the hoops. My only gripes are gameplay ones rather than tech. I don't like how the blocks snap to the move - if I want to jiggle a block that has already been put in a tower, I'd prefer for my move to snap to the block. Several times my tower has collapsed as it basically rips the block out. Also, on the levels where you get blocks dispensed out of little circles on the right, you can't seem to get a preview either of the size, or the materials, whereas you can find out the materials when the block is on the floor by pointing at it. Overall though definitely the pick of the release titles for me.
Not tried TV Superstars demo or Hustle Kings yet, will try and get to them over the weekend.
Generally I'm going to have to spend some time working out the sweet spot for distance. A lot of the games seemed to want me to be closer - I was sitting about 10ft away and sometimes Start the Party would ask me to come closer.
