This year I hope there's 2 new exotic guns like last year, they shops do this each year.
If you're referring to the old Exotic Coin place it was recently moved to a new location here:

If not, the new location is locked for people who don't have any exotic coins.

That image is of the new location, the old one was a little more up north. And if you do have an exotic coin but cannot get it then yeah something must be going on.
