Why does it matter what anyone else is playing? Play what you and your group want to play.
Ultimately, you are right. However, the question has been raised, and this will hopefully objectively answer it.
So far, I'm seeing a fragmentation of the player base, which isn't surprising. We'll see how that develops until Saturday.
We have one member who strongly feels that we should continue with 4e, but he is by far the youngest of us. Maybe the player fragmentation is along age lines, considering the variable appeal of 4e? Subject to another poll, perhaps.
