Not to be dismissive, but that article's sources are the same sources which themselves are just posting things based on rumor. Nothing is confirmed, and there are plenty of rumors going both ways.
The lack of info here is actually quite troubling, considering the launch windows for VZW.
Bionic is set for early August, and the new Iphone comes in September. VZW won't launch a new phone with fewer than 2 weeks spacing, because of the return policies. Either the GSII launches just after the Bionic, and just before the Iphone, or it might be launching closer to Sept-October. That late of a release, combined with the Bionic already being out, and the iphone already being out could really hurt the sales of this device here. If it launches that late, without LTE, I almost see the phone being somewhat irrelevant, especially if the Bionic is even a moderate success.
