Contrary to what many people actually believe, HTC does very well with updates, yes, the one released 4.1.2 instead of 4.2, but it has plans for update very soon, and is already seeing its first update, a month after release. The droid DNA has seen 2 updates already and it has been out 6 months, and also has plans for update to 4.2+ sense 5. While Samsung has a large fanbase and an even larger marketing fund, I hear nothing but complaints about the s3 not receiving updates. If updates are important to you, you should probably look into the Google editions, or a nexus 4.
