I've only heard rumors of "summer". But I, with absolutely NO inside information, like Father's Day, June 17th.
As for being worth the wait, is there anything being discussed for Galaxy S3 that seems like a "must have"? If you answer "yes", then wait. Or, is there anything on the One X that will be missing on the S3? If yes, there's no need to wait. Finally, if you're still on the fence, just wait.
I waited nearly 3 years from the time I first decided a smartphone would be useful to me. I don't at all regret the wait--I'm well satisfied with my S2. Now if they'd only release ICS for it!
Thanks for the reply. I waited for ICS to upgrade from my Blackberry torch. I checked out the HTC one X and it was awesome next to my torch. I've heard nothing but great things about Samsung phones so that is why I was intrigued about the S3. From all the review I read.. it looks like a toss up over great phones.
The problem I see with the HTC OneX is the limited 16GB storage with no ability to add to with an SD card. The SIII will have that SD card ability as well as the ability to remove the battery (a second battery if you are a heavy user).
