It's called 'Destination Arcade' and features a tab for 'New Arrivals, 'The Mall' and 'News Feed' to get you parting with Microsoft Points quicker.
"Next week we'll be launching another way to browse content on Xbox LIVE Arcade and we're calling it Destination Arcade," blogged Major Nelson, reports CVG.
Basically the current navigation is too much of a pain to get through is Microsoft's way of thinking and so gives us something a little flashier (and a bit more PlayStation Store like). It seems to split into 3 sections; deals of the week, new titles and all games.
It lets you sort through XBLA games by "price, community rating, and more!" Some shots of it have been released and it does look pleasantly more organized.
"With a growing library of over 250 Arcade games, Destination Arcade will allow you to discover new games and content you enjoy through an easy-to-use visual browser," he continued. "Also, stay up to date on the latest arcade releases through a news feed and also find out what games your friends like and recommend."
This all new 'Destination Arcade' goes up in the US July 14th and is accessible through the Games Marketplace section of the dashboard.
