I am pretty confident to say that the tower right next to the Southfield freeway just north of West Chicago has been upgraded to NV. I drive past it almost everyday. I drove past it today and it sure looks a lot more cluttered up there; i.e. more cabling and I believe RRU's I definitely saw some new longer panels up there.
I'm going to try and get some pictures tomorrow morning; the site is right on the service drive so I should be able to get some great pictures.
P.S. - I didn't see a LTE connection on my phone, but I was doing 70 when I drove past it so..... I'm going to try toggling airplane mode a few times while I'm taking pictures tomorrow
