So, my honest breakdown of the Incredible 2 and the Thunderbolt honestly comes down to 4G vs. Global. Where ever you live, if you have VZW 3G right now, you will almost certainly have 4G LTE by 2013, so the question you have to ask is do you want the ability to travel to 220+ countries?
If no, I would have you hop on the 4G train now before tiered pricing hits. If the pricing ends up being more cost efficient than the current $29.99 unlimited plan, which I doubt, you can always change to the new data plans. If not, you are grandfathered into unlimited 4G data usage. Ask any former Alltel customers about their 3G internet BSP plan. Unlimited internet use for $60 a month was not a bad deal, and still beats out tiered internet plans.
