Wading through this, as someone who has the second edition books, I really can't see any reason to buy into the remaster. None of the changes are interesting enough to be worth the money - especially _not_ multiple Player core books that are essentially required because basic classes are split between these splat books. That's a WOTC level money grub.
As it stands, I can take the core rule book & basic bestiary & dice and play. More than good enough.
I understand the legal reasons for the changes and that some other changes are being hammered in using that excuse as well since you're going to version 2.5 (in all but name) anyway.
But without a single volume softback, I won't be buying in and will simply keep using 2.0 instead, perhaps house ruling anything actually interesting (traits if the system is actually usable for example). I probably better buy one or two backups of the older core rule book while I can before this replaces them on the shelves.
