I find it somewhat dubious that the "New 3DS" will fly off the shelves.
Majora's Mask remake exclusive for the New 3DS could be a start.
If they really
wanted the system to sell, they'd make the new Ruby&Sapphire remakes exclusive to it.
If they really really
wanted to sell systems they would make it so I could hook it up to my tv. How cool would the new model be with audio video out and a little button to change display from screen to screen on the fly?
Ohkay ok, I'll take it without the display switch function. Just let me play Dragon Quest 4-6 on my TV already dammit!
Lets be honest though, if Nintendo's aim was strictly sales and to increase profits there are a TON of logical ways they could increase fan-base and interest. I do have a certain respect for any company that shoots themselves in the foot economically to make a product the way they want but in Nintendo's case it seems to yield products that are less appealing to fans which is what really baffles me. Between ports that could be available, functionality, new designs for hardware, 3rd party support, ad infinitum... Nintendo could really "fan the flames" in terms of sales and interest if they wanted.
NOTE: Yes, I sound like a broken record about this functionality (the TV out thing) and have been wishing for it (vocally within these forums) for years. And no, I will not stop.
Seriously though, at this point, methods for playing DS and 3DS titles IS NOT far fetched.
