I found it strangely liberating when I didn't switch - suddenly, there was no release schedule to stay current with, there was no pressure to buy new books, and I could do whatever I wanted with the settings safe in the knowledge that my stuff wasn't going to get superseded. (All of those things were technically true before, of course, but it felt different.)
As long as you and your group are happy with what you've got, go for it! The only issue comes if some people want to move and some don't. In which case, I recommend discussing it like adults, and coming to a compromise - can you maintain two campaigns? Can you take turn about between editions? Could you put together some sort of hybrid? Or, if it comes to it, could you consider abandoning D&D altogether in favour of another game - that way, nobody really gets what they want, but you do get to sidestep the issue entirely.
