Will gamers ever break the stereotype of the overweight, goatee-wearing, 30-year-old virgin who works at a comic book store, wears a t-shirt that says "Han shot first!", reads erotic Sailor Moon fan fiction, and still lives in his parent's basement? It's possible, but not likely; it seems like for every 1 gamer who breaks the stereotype, there are many more who reinforce it.
Although it does seem somtimes as though things are changing. Certain celebrities (Vin Diesel, who is pretty much the polor opposite of the stereotypical gamer, being the most notworthy) have publically aknowledged that they're gamers, and bands like Weezer have included D&D references in their songs, so maybe some day down the road gamers will be viewed in the same way as sports fans and outdoor enthusiasts are.
