well, looking at the trailers for LoS, the camera angle does shift angles as you move (the armor battle, for instance), i don't see why you coudn't just get it to shift when you want it to without sacrificing quality. unless areas that change viewing angles are rare and require additional time and effort that they don't want to extend to the rest of the game.
course, i want the ability to zoom in too (like in Legacy of Darkness), but maybe that's just asking too much.
update:
i decided to play some Lament of Innocence again, just to get used to playing a Castlevania without camera controls again. it's sad at times, but i'll live. to make things more challenging the only save i am allowing myself to use is the one near the central hub, i'm not using the map, and i'm not allowed to purchase any potions from Rinaldo. man its fun.
i wonder if they'll have a map in LoS? its kind of nice to try to navigate by memory instead of going on autopilot following a map. LoS should be quite linear, so there might not be any need for a map. And if the repetition is a lot less than LoI or CoD, you really won't need a map.
