i'd say first 30 mins was a 4-5, pretty much what i expected crytec was a big surprise (i'm from germany, so there is a little crytec bias 
) and the announce trailer looked decent (albeit a little too god of war-ish)
last hour or so a 1... or even lower. espn will not be available where i live. dance game, fitness game, pet game, sports game (running on the spot... anyone remember the avgn "NES gadget" video?) are already available, and as with guitar hero or rockband and so on there is no real need to re-buy them just for upgraded graphics and two new features in my opinion. racing... erm yeah i will much rather use my wheel and the star wars game looked pretty bland. in addition some of the performances were pretty awkward/embarrassing.
overall feeling: pretty much a gigantic letdown. biggest part of the show was not aimed at me i guess, but i expected at least ONE good "hardcore" natal game (not shooting, but something with game-play/mechanics depth). voted 2... for the pretty good demos in the first third.
