I'm inclined to agree,
Last year just before it was pushed past the end, we were told that they just had a few big problems to sort out before they would be ready to release 2.5.
The biggest was how to render large forests, The other was re-texturing a bunch of items.
Both of these I would think would have been helped by developing the Normandy map.
A lot of work was done on the caucuses last summer.
But we will see, I will be more than happy to stick with 1.5 and 2.1 if I have the hornet! :D
