am gasit un articol pe n4g.com despre problemele pe care le-au intampinat producatorii cu Natal. Nu uitati sunt doar zvonuri!!!
NATAL: price and technical problems, our information
We know now, developers are more likely to have received the development kits, and even under confidentiality agreements, some languages are loosened. Here are the latest such negative elements rather that we have received:

The latency between movements and their transcription into play would be too large (around 125 ms). A problem that is due to the need to correct the interpretation that makes the human body Natal.
The detection of body would experience further problems: being too close to a sofa, for example, the system would detect a second human to not exist.
The system would function properly in direct sunlight or in total darkness, but would have trouble in low light (not weak enough anyway to switch to infrared).
It should prefer tight-fitting clothing (at least does not interfere with the detection of joints recognized by the system)
Natal detects movements of arms (elbows, shoulders) and legs (knees), but not those in the hands or feet alone.
The development documentation provided with the kits advise against certain types of games, especially shooters.
There should be a minimum setback significant (about 3m for a person to 1.80) so that the system works best.
Finally, and perhaps the most crucial information in the lot, the developers have told us that the price provided in the pack NATAL trade was first established to $ 50 (about 38 euros, as we were saying at the time - given the normal pricing practices between the USA and Europe can be expected 50 euros here) but is about to be revised upwards (no exact details on the contents of the pack, which should nevertheless include at least one game "to Wii Sports").
