I've been playing a lot more lately TG just to take a break from BF3 for a while. Although I like BF3 more, MW3 can be pretty fun for what it is.
As far as the new maps, I did get the Elite subscription and I have played on the new maps quite a bit. My favorite of the 2 is Piazza. There's a lot of elevation changes as you run through an italian village either by street or through buildings. Very nicely done IMO. The second map (Liberation) I didn't like as much initially but it is starting to grow on me. This map is like Central Park basically. The problem is that there are a lot of snipers and can get very frustrating.
Overall I would say that the new maps get a B- from me.
