The Edition Wars are never over. People are still fighting for OD&D and 1e so what makes you think that people won't be passionate about 4e and 3e? I care becasue I like the game enough to spend way too much money on them, travel hundreds of miles to meet people and play at cenventions and game days, and post to a message board about them. THe day I stop catring is the day I'm not playing anymore.
Uh, ok.

I care about Pathfinder, Fantasycraft, & Trailblazer. Don't care about 4e. If someone's happy with 4e it doesn't really impact me. I'm not suggesting people abandon their passion for their hobby, I just don't know why people are trying to "convince" the "other side" in 2010.
