It kinda is. Ever since the close of the D&D fad in the 80s, the pattern had been consistent: a new set of core books would sell really well compared to the trailing edge of the prior ed, and sales of subsequent supplements would trend down from there. It's even held.The definition of insanity is doing the same thing over and over again and expecting different results.
Depending on how you count, we've had 3-5 D&D PHB's released in the last 15 years or so. A new core set every three years? That's a ridiculous business model. It's a huge risk. It's not like a new edition is guaranteed to succeed is it?
The difference is that 5e is putting out a lot less in the way of subsequent supplements to sell less well.

Depends on how much design effort goes into into it. Publishing isn't the hugely expensive undertaking it used to be. Probably 5e, which is - quickly hits the thesaurus for things that sound better than 'derivative' - an homage to the classic game, did not take undue development/writing effort compared to the other modern eds. Still, gaming books of similar page count to a D&D core book get kick-started all the time, so it can't be that crazy.How many hundreds of thousands of dollars, if not millions, did they sink into each new edition?
The best thing to come out for 5e since the core books is probably CoS. It's not exactly new or original. It is, OTOH, good. ;PInstead of trying to sell us, yet again, the same bloody book, they're actually doing new, original material
Martial Power (and Martial Power 2).Good grief, I have or had, on my shelf, a 2e Complete Fighter, a 3e Sword and Fist, a 3.5 Complete Warrior, and there was also a 4e fighter book whose name I forget.
YES.Do we really need a 5th fighter book? Seriously?
Not so much, really. Setting material is easily adapted from one ed to another, it's the crunch that needs to be updated.Thousands and thousands of pages of material for given settings, but, apparently, we need to churn out more and more?
No question it's good business. Doesn't stop players from wanting more.What blows my mind here is how anyone can look at the history of the hobby, where every single edition that had higher release rates failed after three years, and think that a higher release rate is a good idea. Let's not forget that 2e, with the highest release rate, nearly shut the doors for good.

As long as we do get /something/ crunchy each year, I agree.I dunno about you folks, but, I'm perfectly happy with a sustainable release rate that is hugely successful.
