In the Double Impact 2 announcement video, at the very end. Although he's on a different card. Hitman back on URL, even if for a 2v2 is huge IMO. It's probably Gun Titles vs. Hitman/Verb.
2017 is the year of the returns to URL. Rich Dolarz, JC, Qleen, Rich Dolarz, Chef Trez, O-Red, the list goes on. Maybe we'll finally get Bigg K too?
Rich Dolarz has been pretty bad in his other attempts to come back, so I can't say I'm excited, but we'll see. Yung Ill vs. Rich Dolarz forever a classic.
EDIT:
Tone Montana is back too. Even though he bodied himself last tine, I'm still excited. Best gun schemes of all time IMO.
EDIT2: URL:
T-Rex vs. K-Shine.
EDIT3: Oh shit
Midwest Miles and X-Factor teaming up for Double Impact 2. I don't have high expectations given their recent track records, but they have potential.
