Piratecat said:The big problem with this is the same one that TSR had: too many similar books means buyer confusion and paralyzation. If there are four similar books and you don't know which one to buy, you buy none of them.
Scientific American had an article on this recently. You can literally overwhelm the prospective customer with too many choices. What with all the d20 product out there (including the stuff from Wizards) we could be seeing the phenomenon in the RPH.
The convenience store chain AM/PM has an advertising slogan, "Too much good stuff". Which they use in ads showing some schmuck blowing his bankroll by getting everything in sight. It's funny, but that's not how we work.
When faced with 'too much good stuff' we're more apt to say, "stuff it" and go somewhere else. Producing annual editions of the core rules would be another case of, two much good stuff.
And what if the changes weren't just cosmetic?
