Just a unique group, only QB's who can keep up this style of play is Kaep and Cam. Reason being they have some size to them so I can see them being a little more durable. RG3 and Wilson due to smaller frames will tap out sooner then later. So their game will have to evolve as they grow older and rely less on the run.
Not saying that means scouts won't be intrigued by a "athletic" QB but at the end of the day a prototypical 6'1+ pocket passing QB will trump most "athletic" QB's. Luck, Manning Brothers, Flacco, Ryan, Brady, Brees, Rodgers, Roethilisbger etc.. all have some mobility but at the end of the day when it's crunch time they get paid to sit back and pick your defense apart with their arm.
