UPDATE: Just got back from Odeon Leicester square to physically pick up our tickets for Star Wars Episode 3: Revenge of the Sith.
I had a look at the new seating plan that will follow the Odeon's refurbishment and it turns out that our front row, rear circle seats are AWESOME! and are in the exact middle of the row meaning that we will have a fantastic view of the screen!

All's well that ends well then!
