I was talking to my friend (a PF1 player) at GenCon that a new edition or update is likely in the next couple years. His comment, "it seems a little soon for that."
I explained to him that time moves differently now that we're adults, and that 5e has already been out longer than many other editions. He has lamented not even really delved into this edition, that he was waiting to introduce his group to it until it had "settled in."
I know this anecdote isn't really relevant to the current conversation, but I found it amusing. And it's also worth noting that gamers who don't buy stuff are obviously not the target audience.
