Will Godzilla vs Kong have a 3rd Monster (and another question)?

I have a sneaky suspicion since watching K:SI that since Kong is a antagonist and along with G14 sharing the same characteristic they will somehow meet up, fight, then some new protagonist will show up, force the 2 kings to unite for the first time in like 55 years and beat the new MUTO out and then they go out for tacos to celebrate the union. I know the taco thing seems a bit far fetched but you never know.

that's the new trend of movies that pit two popular icons against each other seem to be heading. They might team up or its a tie in the end. So far every movie featuring this kind of match up tends to lean against except one movie, the original King Kong Vs. Godzilla(1962) movie where in the end you at least see King Kong swimming away, revealing that Godzilla was at the least vested by Kong.

I hope they at least show a clear victor of one battle between them. We all have been waiting for this kind of rematch for a very long time.  

 I am just more excited to see the new design of this new MUTO. 

By the way, as of today there is 2.8 years until Godzilla vs Kong and 1.65 years until Godzilla 2. Just can't wait for both of those movies.

I hope that there isn't a third monster, I want it to be just Godzilla and Kong, but I won't be surprised if it happens. If it does, I hope it's done better than Batman v. Superman

If they are doing a 3rd monster, it would be interesting if it is revealed that the 3rd monster is an out of control human created monster that was meant to originally protect humans.

maybe after GKOFM is done the entire world is sick of monsters and Godzilla destroying their cities and killing many people in the process they want a counter MUTO agency. That agency develops a new gigantic mecha-unit, but there is complications with the robot, like getting permission from the president to get it deployed. so the agency hatches a plan to kidnap Kong from skull island(since they know where a MUTO is they want it to destroy a city in order to force a their mecha-unit to deploy), then Godzilla shows up. Kong fights him. then they meet the 3rd monster. the mecha unit.(since Godzilla and kong had robotic versions of themselves in the past this would be a fun way of both of them having a common enemy). they team up!
