While consoles are pretty much limited until they're succeeded, the same does not go for portable devices, like phones, pads, and kindles. While keeping up with the latest tech is not feasible in the short term, due to a low amount of immediate adoptees, there always comes a point where more people will have the newer technology than those who are still holding onto the old. Not only could such updates improve things visually (I've seen lots of requests from Kindle Fire HD users to update the graphics to utilize the higher resolution screen), but it could also remove alleged technological limitations that affect gameplay, such as the opaque ramps on NGG. Are there plans to gradually update the graphics / engine?
