Major Nelson has dropped a few interesting bits of data regarding Xbox Live since the launch of the New Xbox Experience. Overall, sales of content on Xbox Live Marketplace -- including games, movies, and TV shows -- are up considerably. Probably most impressive is the claim that Xbox Live Arcade sales have "almost tripled" since launch. Specifically, the sales of games with Avatar support -- UNO in particular -- have gone up. A Kingdom for Keflings, which includes Avatar support and launched the same day as the NXE, had "the second-best first week of performance ever" (what was the first, we wonder?). Another interesting tidbit, the number of Friends added per Xbox Live member has increased by 33% since launch.
