Well, we have few other details beyond what you see in that invite above, but you better believe we'll be in New York City on August 29th. We're definitely expecting Samsung to announce a Galaxy S II launch in the US, especially given Samsung Mobile President Shin Jong-kyun's promise of a release "sometime in August" -- along with that intriguing II graphic in the invite up top. We also have on good authority that the S II will be launching on several carriers at once, which likely explains why Samsung is putting on the show, rather than deferring to a single partner. Check back on the 29th for the full scoop, and head on over to our full review to whet your appetite in the meantime.
Update: We noticed that the invite image itself is named "Galaxy_S_II_Invite_v2.jpg," so we're gonna go out on a limb here and say that the S II will definitely be released.
