To address the OP, what was promised or at least hyped/advertised as what Kinect was capable of doing and being differed greatly from what Kinect finally was more or less boiled down to overenthusiastic marketing leading to unrealistic consumer expectations. Just watch the original E3 Project Natal hype reel to see what I mean.

In all fairness, Kinect IS actually capable of doing more than what has already been seen (and will be seen since it's on the verge of being replaced), but designing a game that actually utilizes the specific advantages Kinect provides is, as we've seen, difficult at best. It's a lot easier to go with more obvious uses that are much easier to produce and in far less time. Unfortunately, given the target audience of Kinect, no one was really willing to spend the AAA resources to produce a game that wouldn't be well-received by the demographic that typically buys such games.

Lastly, Kinect seems more like a work in progress than a finished product. In the interest of keeping costs down (lower res sensors, no co-processor, etc.) and due to the limitations of the hardware (CPU resources, memory, etc.) it was designed to run on, there's only so much than can be done given the amount of data and bandwidth required to get accurate body/joint recognition software to run.

Still keeping my fingers crossed for Kinect 2.0 integration with Xbox 3.0 since improvements in the technology could allow for so much more, given the proper effort and care in the games that use them, but there's always the chance that MS lets Kinect die off quietly like a lot of Nintendo and Sony peripherals have in the past.

SIGH. People are actually defending Kinect?

FACT: Kinect sold because of marketing, and limited consumer choice.(Most bundles available at the holidays were Kinect)
FACT: Kinect does not have the content. Look at sales for its exclusive games, horrible considering its install base.

Kinect may have sold much more than PS Move, but they are both failures on what matters........games.

The Move is a hybrid peripheral so I dont understand how they completely ripped off Nintendo. Secondly the Move wands had been in R&D before 2004 and Nintendo had not released ANY details about the Wii at that time.They already had the eyetoy and they knew it was limited and coupled it with the want three years after the original Eyetoy even came out. Of course it see undercurrents of bias in you, so I know your motive regardless of anything I say is to trash it. Anyway, watch this video, of the small amount of marketing the Move got they pretty much alienated casuals and the move became a core draw, because its potential was beyond the Wii and Kinect. The device was marketed more in a focus sense to a more segmented part of the larger market that already existed.

dont know why anyone is wasting time with phenom is he cant understand that the money that MS put into advertising Kinect is about five times higher than that of Move then he is a fool plan and simple

True, the amount Sony paid for their Move commercials is probably near the amount Microsoft paid Usher and Neyo to perform at their E3 and Kinect launches combined. 

Not going to address any of this, because we both know why Move was created. I wonder how it took Sony so long to develop it. Sony just conveniently finished it after the Wii took off, yea ok. A video can't prove it got a small amount of marketing lol, that video proved if anything, Move was marketed. I guess Sony had no belief in it taking off either, ripping off Wii sports would probably do that. They didn't alienate casuals lol, eyepet and sports champion prove they tried and just couldn't pull it off. You have the most excuses in the world. This is off topic so ill leave it at this, Sony marketed Move and even made software that was already proven to be popular with casuals, it just didn't work.

And? So Move failed because Kinect was more advertised? Wow, please keep the excuses coming lol.

When are yal going to actually prove Move lacked marketing? Maybe everyone saw it as what it was? A wanna-be Wii Remote maybe? It even came bundled with a sports compliation, I wonder where they got that from?

Interesting. I only saw the butler ad.  I heard they were more but I never saw them.

People can moan all they want, Kinect works great for a lot of people myself included. I don't care if I can't play "core" games with it because I don't just play "core" games. I could've got the Move or a Wii but the Wii games that interrest me are dancing games... Kinect does them better... on PS3 no Move games interrested me and just like one pointed out, navigating in the menus with Kinect is something else once you're used to it.

I'm also glad MS invested in the technology and hope they release a new more powerful version along the next Xbox because really is a lot of possibilities with this device. If people on forums can't see past their nose then we can't do much for then.
