uhh, once again, it's been announced as a DS game AND it comes out in japan this year- 3DS doesn't come out till next march i heard
It was announced to on the DS handheld and considering it was announced before the 3DS, they may not have been ready to announce the new handheld before then. Its a very likely guess and probably going to be like the GBC era, Gold and Silver compatible with original gameboy, extra's for playing on new hardware.
3DS is
estimated to be out in all territories by March 2011, which I believe the final region will get it in, Europe. And much like every other console, America and Japan will get it months way before EU and like the original DS and Wii release, will be in November this year.
Every thing is guess work at this point, don't bother repeating your opinions as if they are fact and presume they totally debunk some one elses point, as you don't seem to have thought over the announcements and how people are coming to the conclusion 5th Gen will be on 3DS.
These pictures says otherwise:
Market towards and compatible for are complete different subjects. I bought both of these games on launch day, and they are for the
Gameboy built closely on the
engine for Pokemon Yellow.
With your logic, these pictures say otherwise:
^ Pokemon Silver cartridge, notice the notch on the top right? The original gameboy cartridges have this because the original gameboy locks the game into place when you flick it on, and a plastic bit will cover that notch to prevent the cart coming out.
^Generic GB Colour cart, notch is gone, will not allow the original Gameboy to turn on. Even if tampered to remove the plastic bit, will display a message stating it is incompatible. Crystal also had a cartridge like this.
