I remember reading that, and the general concensus at the time was that it was simply a mistake. Its unlikely that an LTE GS2 would get approved at the same time as the Droid Charge, and be given such a similar model number. I would still say there's a chance, but it certainly isn't looking good. There has been NOTHING official, nor any leaks with believable info regarding an LTE version of the SGS2, just our wishful thinking.
As far as the new Bionic having OMAP4, that hasn't been released either. Myself and others see it as a logical choice, considering Tegra2 was mentioned to be causing some of the initial problems, and Moto has a history with TI. BMX mentioned that Moto was redesigning it to keep up with bleeding edge specifications, and I personally don't see how they could do that without an OMAP4, though to be honest their statement could easily be marketing BS. I think the OMAP4 rumors first started, however, because many people assumed the Targa had it, since it was supposed to be the next big thing, and the launch time seemed right. However, at this point, we don't even know that the redesigned Bionic is essentially the Targa or not.
