I'm going to have to disagree with you on that one. EA is putting all their effort into this game to make it the best sim game ever. Will it sell more than 2K? No, of course not, 2K is going to be on current gen and next gen. If EA releases a video now that is half done what do you think the gaming community is going to do? They are going to tear it to shreds like they did the last 2 titles.
EA has been down this road before and knows what NOT to do. They see what 2k has been doing over the past couple years and the features it is. They know what has made 2k successful as well as things that the community hates. Such as can't block dunks, or canned dribbling animations, or infrequent roster updates. And what has EA come out and stated? They have BounceTek to counter dribbling animations, they have up to the hour updates, and you can block dunks. Live will have all those same features as 2k if not more b/c there aren't any limitations on the next gen hardware yet.
From a review I saw, they said you can see the stitching of the shoes from a afar. This just tells me EA is going all out on this game. They are being perfectionists. The game WILL come out. Be patient, we got 2 months till launch. Best early christmas gift you can ask for. haha
