Look, if history shows us something, it is Apple puts it (it being whatever they refuse or don't offer) on stage when it is least expected to.
Also, if history shows us another thing is that Steve Jobs is in charge who shows what and when and where. In this case, take the iPhone 3G S for example. It was Phil Schiller who announced at WWDC, not AT&T Mobility CEO.
For the more reason, this Verizon event will be something else. Everyone assume it is Apple backed due to the fact that Gizmodo didn't get an invite. That's barely evidence even though they had a problem with Apple; if people think it is big evidence, how wrong they can be.
This event is most likely for LTE plans and devices with Android shipping as well as Android tablets.
Now as per iStuff on Verizon, Apple only on their stage, with their people on their event will it be announced. That's how it has always been and knowing control freak Steve Jobs, that's how it's going to be for a long time. So, Apple event in January, iPad 2, Verizon model available very likely. iPhone 5? Well, I will not be surprised if it's released this year during WWDC. Also, the AT&T contract is stated to end this year might end when the iPhone went initially on sale... if that's the case; which I doubt.
