I'll also be getting this. Like Flame, I also saw it a while back on Amazon, and had been tempted to pre-order it then. Heck, I've pre-ordered the Dracula's Tomb edition of LoS2 mainly for the artbook. Shame that there won't be an Alucard figurine included.
Unless that figurine labelled as 'The Lieutenant (Alucard)' on GAME's website is to be believed, which seems to hint towards Al having a second, more monstrous, form. This label was very quickly changed to just 'the Lieutenant', however.
One of the things which MS have definitely done well is the artwork for these games.
While I don't know of a specific full artbook for the main timeline, aside for the little ones which have come with the games (such as the SotN mini manga, and the POR 20th anniversary special edition), Ayami Kojima's artbook Santa Lilio Sangre has a good sized collection of CV artwork from her days on the series. If you like her work, the book is well worth it.
Spoiler for potential theory.
