I know I know, i normally hate these topics too, but I had to make it anyway because a thought occured to me.
Obviously do to the massive success of the SP, Nintendo can be expected to use a similar design with thier next handheld, it only makes sense. Of course, they are not going to want to make it bigger than the GBA SP, and yet, a higher resolution seems like a must, as surely Nintendo realizes that graphics cannot be imporved any unless there are more pixels to work with....
So my best is that Nintendo goes with a screen that is about the same size as the one the GBA uses, but with a higher resolution, that is, one with smaller pixels. (for comparison, the GBA screen has pixels about the same size a 15 inch 1024X768 LCD monitor, perhaps the next GBA with have a screen with pixels the size of a 15" 1600X1200 lcd panel?)
A 300X200 screen that was still the dimensions of the GBAs screen would provide absoloutly incredible sharpness and detail, and next gen Gamboy games would certainly live up to the best playstation games. (talking 2d here, i do not think 3d makes sense on a handheld, not because of powr issues, but becuase of control issues, 3d needs buttons and analog sticks that arent practical on a handheld....)
This however poses a problem where backwards compatabilty is concerned. GBA games would surely be too small to be enjoyable on such a screen, and GB/GBC games would be absoloutly unplayable.
So the question is, does Nintendo forgo backward compatbilty with the next gameboy in order to have a no compromise screen while not increasing system size? Does Nintendo continue (stupidly) to use the same low res screen? Or does Nintendo increase the system size over the GBA SP in order to use larger screen that will still allow GBA and GBC games to display at a reasonable size?
What do you think?
