I have a very strong feel this will happen next year, as it will be the past (Mysterio), the present (ADR) and the future (Sin Cara; the wrestler formerly known as Mistico).
This match will be a slober-knocker as JR would call it, and in my mind only one thing would complete it, Guerrero.
HELL NO—Not Vickie...
Eddie would be the perfect fit, and if he was alive but a substitution may be what is needed.
Maybe the WWE could fit Chavo Guerrero in where Chavo will say his Uncle was the best Mexican WWE wrestler.
This match would be one for the books and i hope WWE will do this.
Probability this year - 0/10
Probability next year - 6.5/10 (excluding Chavo) 3/10 (including Chavo)
Probability at future events - 9/10(excluding Chavo) 4.5/10 (including Chavo)
