To be exact, I'm claiming that we cannot know how large the divide is. That there is a divide is self-evident. But, then again, there was a divide LONG before 4e came on the scene. How much has 4e exacerbated that divide? I have no idea.
Ah, a much more reasonable stance than the one I thought you were taking.
And you're right, we don't have clear evidence to measure the size of the divide.
However...
Turn it around. The continued existence of OSRIC alone shows that players didn't switch to 3e. Does that mean that there was a massive divide in the player base with retro-clones and the like? Does Mutants and Masterminds mean that 3e wasn't as successful as it could have been?
Just because there are other games on the market does not really mean anything.
Two questions:
1. Do you think that Mutants and Masterminds is in competition for players in the same way that OSRIC, 4e, Pathfinder, 3e, and others are in competition? (I'm trying to point out that Pathfinder is not an "other game on the market" so much as "fills the same niche for D&Ders as other versions of D&D.)
2. Do you think that the OSRIC divide is anywhere close to the divide between Pathfinder and 4e? Do you think there are as many people playing OSRIC as Pathfinder? Honestly? I know it is tempting to say we can't know, but what is your honest guess (give a percentage for how confident your guess is if that makes you more comfortable).
Because I don't see an OSRIC forum here on ENWorld, I don't see the amount of supplements for OSRIC that I do for 4e or Pathfinder, I don't see people comparing OSRIC to 4e or to Pathfinder in thread after thread.
I think it's pretty clear that, whatever the size of the divides, that the gulf between 4e and Pathfinder is larger than the gulf between OSRIC and Pathfinder or OSRIC and 4e.
Overall point being that, no we can't measure the size of the divide, but we can gather data and impressions (two separate things, I'll grant) that the divide might be the largest one for players of D&D that we've seen (particularly if we lump 3e/3.5 holdouts with Pathfinder converts).
