The problem I have with this overall is the concept of the "Fourth" Character. But before I elaborate on that.
Dave Cox promised that even though all the Characters use whips, their animations would be different. I see Simon doing the moves that Trevor did... which hipster Gabriel did earlier, such as the "Guillotine" as shown in the trailer. I would hope that Simon being raised by barbarians and he would at least have a different combat style not to mention that unlike the combat cross, the Vampire Killer whip isn't auto-retractable like the Combat Cross is. I understand that since the traditional spriting days, all the Belmonts were quick at retracting their whips but this makes Simon even more powerful at combat if he retracts his whip as quick as the Combat Cross not to mention without the use of stake, grappling hook and the spiked chain upgrades. My best understanding is that Simon will upgrade his whip to the standard chain or even a combat cross considering how long Vampire Killer seemed.
That being said, I understand that we're judging the place of events for Gabriel judged on his appearance, but I don't think they will do the skin add-ons on MoF characters such as the skin-change of the cyclone boots, seraph shoulders and sub-weapon add-ons due to the limitations on 3DS, the changes I speculate is the change the whip for Simon or Alucard's true identity being revealed away from Trevor's appearance and I don't know what they will do for the fourth character. So judging the events for Gabriel based on appearance isn't much of a clue and the seraph shoulder's detail is just made for cosmetological purposes to Gabriel's armour seem much cooler. If anything, Gabriel would be either explaining some things about the Prologue prior to the LoS events or as a flashback. I don't see or wish to see Gabriel as the fourth character because, Trevor is supposed to have that similar gameplay and the whole game is supposed to take place in the Castle. Good guy Gabriel being in this game would be just out of place unless they are planning to make it seem that Gabriel somehow makes it into the alternate reality exploring the castle that is probably changed alot due to the place being the creature of Chaos... and then having to fight himself. There would be alot of conflicts in the story and even if they manage to tell it, it's not worth being explained since there is alot more you could do to make the story better. Being that all the Characters would have a similar combat style and the same choice of weapons, the idea seems a bit stale for some reason and now having Gabriel as the fourth character would only make it kind of worse. My only guess is that Gabriel is going to be a pseudo-fifth character in which you play as him for a short time, which is possible since none of us have experienced the weird manticore looking creature. I just believe that Gabriel should not be the fourth character.
