Last night, I said that if Doom Slayer is in fact deconfirmed for Fighter 5, that my next prediction would be Monster Hunter.
But after sleeping on it, I'm just legit stumped as to who Fighter 5 is. My gut has moved from Monster Hunter to Lloyd due to a few facts:
1. Lack of his previous Mii Costume.
2. The recent trademarks, most notably this icon:

3. Sakurai seemed to no-so-subtley hint at another Bandai-Namco character in the Terry trailer. This is not unprecedented. Remember the red eye and K. Rool?
So again, going simply on evidence, since Doom Slayer seems to be dismissed as Fighter 5, Lloyd seems to have the most hard evidence in his favor.
I'm not saying that Lloyd is for sure the next fighter, but I always base my predictions on evidence rather than blind speculation, so I am essentially forced to throw my had behind Lloyd.
