Microsoft has managed the impressive feat of talking up the success of the recently launched New Xbox Experience (NXE) dashboard update without really revealing much at all.

We sense the shadowy hand of the Microsoft PR machine at work behind this one, although it was left to Xbox blogster Major Nelson to make the announcement. He thought we’d find the data “interesting”, he says.

Well yes, but more intriguing is the reason why MS didn’t feel the need to share the specifics. Hmmm, maybe it’s to stop Sony from attempting to steal their thunder, as happens with yawnsome regularity these days. Anyway, those NXE stats in full:

- If LIVE were a U.S. city it would be the largest, with over 14-million members. The equivalent of New York City, Los Angeles and Chicago combined.
- Since the New Xbox Experience launched on Nov 19 the number of new friends added per Xbox LIVE member has risen by 33%.
- Xbox LIVE is not just games: With more than 45 global network and studio partners, and Netflix in the U.S., offering more than 30,000 movies, TV episodes and music videos in both high and standard definition.
- In the past year the average number of unique visitors to Xbox LIVE each day has risen 66%.
- Movie downloads increased 49% and TV episode downloads were up 30% the week after launch.
- Xbox LIVE Arcade sales almost tripled in the first week after the New Xbox Experience launched.
- Avatar-specific titles like A Kingdom for Keflings registered the second-best first week of performance ever.
- UNO, which was updated to include in-game Avatars, saw a 650% increase in sales in just one day.

“Pretty good numbers,” says the Major. We’d like to agree, but it’s kind of impossible to do so until we know what the actual figures were in the first place. More details please!
