I just bought this issue today. Marvel Universe Ultimate Spider-Man just replaced the all ages Marvel Adventures Spider-Man book. Makes economic sense to create a comic book based on the new Ultimate Spider-Man cartoon. Marvel Adventures Spider-Man was selling poorly even though I enjoyed Paul Tobin's stories.

This first issue is written by Man of Action (Joe Casey, Joe Kelly, Steve Seagle and Duncan Rouleau) and Dan Slott and Ty Templeton. The book is divided up into two stories based around the cartoon. First story drawn by Nuno Plati and the second story drawn by Ty Templeton.

There was a free Ultimate Spider-Man Premiere comic in stores last month. I believe that issue was just screencaps of the first episode lettered by Chris Eliopoulis. If your LCS is out, you can download it for free from comiXology.
