Two years firmware updates is no big deal.
From what I can tell, the K-5 got four years of firmware updates 2010 to 2014 (v1.01 to v1.16), K-3 got updates 2013-2016 (v1.01 - v1.3), 645Z got firmware updates 2014-2017 (v1.10-v1.30). Even the modest K-x got three years of firmware updates from Pentax after launch (2009-2012 - v1.01 to v1.03).
Some of those firmware updates (eg to K-5 v1.01 and K-3 v1.02, v1.10, v1.3) added new features and capabilities, weren't just bug-fixes. K-1 has also been down a similar feature-adding path with v1.3, v1.4 firmware too.
