To put on my Abe Simpson hat, "I remember back in Nineteen Eight One or so when TSR - that stood for The Senile Roleplayer - put out the last set of lead miniatures for the original AD&D game came out - yep, they were lead then, in case the Russkies invaded, we could melt 'em down and turn 'em into ammo. Anyhoo, the last set was of a wizard's lair, and featured a large snake. My brother painted the snake bright red, and we lost the wizard, so it basically looked like a rather intelligent snake had a wizard's lair. And since we didn't cotton much to plotlines then, we just pretended that's what it was..."
So, we've seen Dragon and Dungeon die and be reborn before. We've seen official and unofficial minis. We've seen multiple edition wars. At the end of the day, we've all got lots of rules sets, great minis from Citadel and others still in production, and plenty of free content on the web in case things get worse. It's actually a good time to be a gamer.
