I can't believe you are discounting the Gizmodo evidence like it's nothing. Gizmodo even contacted Verizon regarding why they were not invited and they were told "no comment". Even a person without an ounce of logic would be able to deduce that this was influenced by Apple. As far as I'm aware, Gizmodo has never been rejected by Verizon or any other tech company.
As for whether it might be an event to highlight Android devices, I don't know whether you've been living under a rock for the past week, but there was an event called CES where everything about Android and LTE was announced. Why in the world would Verizon hold an event two days later in a city on the opposite side of the country from CES, to announce prices? If I was a journalist who had to make the trip, I sure will be pissed come Tuesday if I had to travel all the way across the country just to hear some prices for previously announced phones.
