Yeah. They seem to have decided to only release the 2 corebooks for it. I hope they change their minds though.
While I think the Books are incredibly well done, and you could probably build anything with it, I would like to see the occasional supplement.
Not necessarily a running line like D&D or WoD (that would be too much), but maybe just one or two a year.
Among things I'd like to see are...
A GM Screen
A White Council book (or just a book of Wizardry)
A Denarian Book
A Vampire book (could probably do all 3 courts as one book, but I'd pay for 3 smaller books if it came to that)
And eventually
A Black Council book (assuming they exist)
I'm sure I could think of more ways to give them my money, but that's just off the top of my head.
