Spring dash update features revealed?

Well, well, what do we have here? Word on the street is that Gamespot accidently posted a complete list of the new Spring dashboard update's features and even posted a demo video (embedded above), but then promptly pulled the article. But, unforgiving as the internet is, they didn't yank all the information before everyone and their mothers copied down all the features and mirrored Gamespot's video to YouTube. And our friends over at MyGamerCard.net were nice enough to round up all of the article's information in one convenient place.

Among what Gamespot posted for new dash features is Windows Live Messenger integration, a new Marketplace blade, more informative "Achievement Unlocked" pop-ups, and a low power mode for downloading Marketplace goods. Gamespot's article and video also state that the Spring update will be dropping on May 7th. Whether Gamespot posted the news prematurely or were posting a very late (and evil) April Fool's joke, we aren't sure. But if this is what the Spring dash update has to offer then what new features are you looking forward to?
