DannyA - There is a problem with the Coke analogy though. New Coke failed. AFAIK, 4e isn't failing by a long shot.
Family Guy may have come back, but Firefly certainly didn't.
There really has to be a time when waving the flag become counter productive. Constantly agitating for something runs the risk of just being written off.
Not analogies- simple statements of facts: other products have been rescued from the dustbin of history due to customer activism.
Family Guy's resurrection took
4 years.
Firefly, while not getting back on TV, was made into a movie. (How good it was depends upon who you ask...)
New Coke failed(ish)- it was still in production as Coke II as late as 2006, and I don't know if its actually been discontinued- because it was an undesired replacement for a perfectly good product.
As you so rightly point out, 4Ed is doing just fine. So did New Coke, for a while. But 4Ed has already passed the point by which the dip in New Coke sales became an obvious problem for the Coca-Cola company.
However, just as 4Ed is succeeding, so are the children of 3.5 and resales of 3.5 material itself. Its not like Pathfinder, True 20, Midnight, Arcana Unearthed, FantasyCraft, Warlocks & Wizards, etc. aren't finding purchase among the "disenfranchised" lovers of 3.5.
While I don't have any sales figures on hand, I have no doubt that 4Ed is the current 800lb gorilla of RPGs. I'd be surprised to find otherwise.
So I'd be curious to see the sales figures for the major 3.5 derived rulesets- aggregated, of course, in order to see just what chunk of the RPG market such games command. That, coupled with an examination of the resale market for 3.5 products, would give us an inkling as to the actual size of the 3.X market. And not just raw sales, but also how sales are trending for the games (both aggregated 3.X and 4Ed) within the industry and the economy as a whole.
What I'm getting at is an assessment of what kind of threat do such games present- does the 3.X market present any credible threat to 4Ed's market share? Is 3.X the 500lb Franken-gorilla of the RPG world? Is it getting bigger? Or is the entire 3.X market smaller than not only 4Ed, but other major games as well?
IOW, did WotC inadvertently create its own strongest competition?
If it has, if the aggregate 3.X market is a continued real force in the overall RPG market, WotC will not simply ignore that. Just like past revisionists of D&D at least examined their strongest competition when doing their design work, so, too will the designers of 5Ed consider what other near competitors (or, in econ-speak, substitutes) exist in the market and
why they exist as competitive threats at all.
They'll ask "Does 3.X- or any other game in the market- deliver something that 4Ed doesn't that could and should be incorporated in 5Ed without changing our overall design?" They'll also ask if there are any designs within 4Ed that ultimately proved to be unpopular even within the game's players, for whatever reasons.
