I fly MCO/TPA <-> IAH regularly, often during peak times, and except for the 757-200 as a plat I have experienced a 100% upgrade rate on those routes (though I typically fly H fares so I'm at the front of the queue). If EWR <-> TPA is similar, and I expect it is, then you will enjoy a lot of upgrades.
