Ms will be given a lot of credit for their tech, every return so far has been positive to super enthusiastic. It looks like they are carefully selecting people allowed to test it.
So far I didn't read any hand on experience from the french sites I consult except for one site who managed to grab to journalists from a pretty big news channel (LCI for the french).
Their enthusiasm is quiet communicative. Whenever this launch it will be in the top hot news of most magazine, evening news, etc. When this will launch the whole world will be watching, this goes so much further than video games.
For those interest the vid is here
I think in regard to growing number of returns about Natal and what it seems MS managed to pull out I would as far as saying that the trend on this board is on the verge of being petty.
This thing is big, I hope to learn more about it soon ( and soon won't be soon enough).
