30% growth is not hard to achieve with a small company - and it's very easy to report for a small, privately held one.
Pathfinder premiered in 2009. The core books are always the biggest seller with an RPG, but it failed to challenge D&D for the top spot at that time, even though D&D was just publishing supplements. PF had two winning quarters vs D&D, when WotC was trying out the new Essentials rules and format, which apparently, didn't work out that well. When they went back to the hardcover format, D&D went back on top until they stopped printing it.
It's back on top now, with only a few books a year against everything Paizo can put out.
No amount of speculation, out of date 3rd-hand statistics, or made up numbers is going to change that.
Its when you look at the numbers though. In 2009 Pathfdiner only game out late in the year and sold 4.4 million doallrs worth. Thats about half or 1/3rd of 5E launch in its 1st 6 months. By 2010 when runmors surfaced Pathfinder was outselling 4E they were getting 8 million IIRC.
5E launch grew the RPG market from 15 million through to 25 million which is roughly in line with Danceys estimates about how much D&D is worth as an RPG brand (5E+Pathfinder roughly what 3E was before the split). 5E/Pathfinder is worth 80-90% of the RPG market maybe more.
So one can take some good guesses abut how well 5E has done. At least 10 million in its 1st year vs 4.4 million in 6 months for Pathfinder) with an upper limit of probably 15 million since Pathfinder players are not leaving in droves it seems (some 5E sales would have come at the expense of Pathfinder probably).
And 5E is apparently doing quite well. One could also take some good guesses on how many core books they have sold on that 10 million odd dollars of revenue. 5E has sold well relative to 4E but it has not sold as much as say 3E did in its 1st year and it seems more likely it is in 2E levels of sales which got around 280k PHB sold in 1989. Its roughly in the middle of the pack in terms of D&D sales with the big numbers being BECMI, 1E and 3.0.
Paizo also had 30% annual growth rate 2009-2012. Once the core book bubble bursts it will be interesting to see how well 5E is selling in year 2 and 3 which is where Mearls said they will know better. Paizo is bloated but someone is buying their stuff it seems.
