Any information on the up-coming 150 coupon tier weapons?

I have reached 150 Crate coupons and i have already exchanged the crate coupons for an M14EBR Scope Camo 2 months ago... But currently What I am thinking about is that...
Should I exchange the coupons for Dual Uzi gold or wait for the up-coming coupon weapons?
So can you tell me... What are the up-coming 150 coupon Tier coupon weapons in Crossfire NA so I can decide what to do...
