I don't know about you, but 5th edition seems to have been made for splatbooks and yet I here we are supposed to get a low book rate.
What sold me in the beginning was all this talk of modularity. There is supposed to be all these supplements that support all sorts of various play options in order for people to tailor the game to their needs. I even look at the rules in the PHB and I see them as usuable to play but feeling incomplete. I see the potential for tons and tons of options. Why create a game that is supposed to be chock full of options, but keep the book count low?
My general feeling is that 5e is more or less equally (potentially) splatbook-friendly as the previous 2-3 editions.
I don't think we'll actually see that many rules modules, not major ones at least. In theory the design space is unlimited, but rules modules require both a lot of creativity and serious technicaly design effort (including playtesting), and I am afraid they sell less than character material. Personally I expect the DMG to be the only book with rules modules until maybe 3 years (not counting a possible psionics handbook).
I do agree of the "feeling incomplete" about the PHB, but not because of the rules but rather because of character material. Half of the classes have only 2 subclasses, domains are miserably few, and rogue and fighter also are especially lacking subclasses (also compared to what we've seen in the playtest). Feats are also not that many. Several traditional spells are missing, although they might be just missing for good and may not have a place in 5e at all. I do expect additional character material to be published next year, but it might be either in the form of supplements or even in an updated PHB enlarged to 350 pages (like the MM).
I think 5E was made for customization, one approach of which would be through splat books.
Yeah I agree, we're used to ready-made customization but it wouldn't be bad at all to go back to a culture of do-it-yourself material
