My humble opinion is this: The 99 game that IGA owes to the people... and that's it. No more from him. While the games were very good, the story was getting to stupid levels. Besides Castlevania is in Europe, not Japan, leave Japan out from Castlevania. You don't see a whip versus a katana, a Belmont versus a Samurai. Gotta give someone else a chance.
On the other hand, if a LOS3 comes out, in any way or another, we will accept it and maybe even like it. In the end of the day, it's up to Konami to decide if the want to paste the name Castlevania to someone with rifles and shotguns storming a castle to kill a Vampire dictator or something. We are allowed to rant about it.
LOS2 is good, like an IGA game, the gameplay is good, but the story lackluster. But at least it's different to recycling SOTN like IGA did for many many years. It worked, it was good, but new blood was needed.
