The description at the link:
"Departing from the contemporary take of the 2d exploratory "Metroidvania" format, this is a true Castlevania adventure."

How stupid is that? In many ways...
Anyway, this collection seems like a scam. Even for LoS fans. Why not wait until LoS 2 is released?
I see it like: "Hey, let's steal a little more money from people before we are done with this s**t, and let's try to fool a few more players who we still didn't fool and don't know how the games are".
And meanwhile, a collection from the main timeline remains unreleased.
I think to do a Castlevania collection you can't do it in one go there is too many titles and it would be super mad expensive.
The best way to do it is a box set that collects all Classic Castlevania games : Castlevania 1, Vampire Killer, Castlevania Simon Quest, Castlevania 3, Super Castlevania, Rondo of Blood, the Igrashi remake of Castlevania 1 and Legacy of Darkness (Castlevania 64).
Then you can have a 2nd box set which would be Symphony of Night Saga or a better title : Symphony of the night, Harmony of Dissonance, Dawn of Sorrow, Aria of Sorrow, Portrait of Ruin, Order of Ecclesia and possibly Lament of Innocence and Curse of Darkness (Although their inclusion isn't necessary). Presto you have two nice box sets to satisfy the majority of Castlevania fans. I didn't include the Gameboy games because other then novelty I doubt most people would miss them and we are looking at box sets that will satisfy and sell (But you know I doubt including them will be major issue so maybe they should include them in 1st box set although its not a big deal).
Basically I couldn't careless about Lord of Shadow boxset all I care about is my downloadable HD mirror of fate.

I wait for it to come out.
