It's all about the 3.5/4th debacle.
Back in 2004, when the 3rd edition revised came out, it was called 3.5, and it got a lot of people angry because they thought WotC was trying to subtly tell people that there would be a 4th edition in 2008.
Of course, WotC came out, denying this, saying there would not be a 4th edition in 2008 and that 3rd edition would go on to continue for many, many years to come...
Then came 2008 and the announcements of the 4th edition, and during the announcement video on youtube, they even admitted that it was in development since 2004.
Then, during the run of 4th edition, WotC pleaded with its fan base to drop 3.5 as it was broken, unbalanced, and unplayable... an odd way to treat one of your former IPs...
Let's not forget that during the last year or so of 3.5, products came out that were barely playtested (as they had gotten rid of a lot of their development team), had horrible power creep, as well as some really odd and questionable changes to the rules... (I'm looking at you new rule on how to price magic items form the Magic Item Compendium!) In hindsight I am seriously wondering if WotC was not already starting to sabotage 3.5 back then in order to get people to adopt 4th more easily...
Basically, this convinced me that WotC could not care less about it's client base and well, I've decided to vote with my wallet...
