To compete in a videogame saturated market and if WOTC is to build up to a "3rd wave" of popularity, the only real choice is to ramp up the eyecandy by several degrees. That may even mean shifting their focus mechanically with a heavier emphasis on terrain. If you look at the relative success of Heroscape or many of FantasyFlight Games offerings, the core sell point is jaw dropping "on-the-table" presentation. I'm not talking rinky-dink poster maps, splash art, badly painted figures, or gimmicky digital hybrid apps, I mean a full fledged, tangible, true 3-D assault on the eyeballs.
While the core game system is absolutely important, I think too much emphasis is placed on it as the soul savior of the D&D brand. Obviously I'm extremely bias due to the business I'm in but to me the formula is simple; Overwhelm their ADHD, knee-jerk, visual "need it" center to get videogame players in the door and then get them hooked on the deeper content. All they need is the right streamlined, visual push and I think a heavy focus on terrain could do that for them.
I mean, what kid wouldn't want a WOW equivalent sitting on their kitchen table?
