For Christ's sake, no. Please, no.
Some people enjoyed the Lords of Shadows saga a lot, and they had their time, some of us didn't enjoy it and we've already waited too much.
It's time to go, Mercury Steam.
Let another studio (Platinum, WayForward or Konami itself) make a new Castlevania.
Be it ClassicVania, MetroidVania, a remake, or something new, but with the look and music of what I like (and many, many, many fans).
Especially the music, since Mirror of Fate looks pretty OK (though it's no Rondo of Blood), but the music stays the same as in LoS.
I'd personally want one of these options:
1 - The return of IGA.
2 - A game like Bloodrayne: Betrayal by WayForward.
3 - A game like Bayonetta by Platinum.
4 - A new game by another studio, provided they don't follow the LoS line.
5 - A remake.
