Black and White to be enhanced on 3DS
IGN have recently revealed that upcoming games Pokémon Black and White Versions will have enhanced features when played on the upcoming Nintendo 3DS console; however, 3D gameplay will not be supported. It is interesting to note that the 3DS's "StreetPass" feature sounds similar to the "Pass By" Mode of the C-Gear. This is similar to enhanced features the games have when played on a Nintendo DSi or Nintendo DSi XL (DSi LL in Japan), which allows Video Chat using the Xtransceiver.
Earlier last year, it was announced that out of numerous developers, The Pokémon Company were given priority with development kits of the new console. It is likely that at that stage, Black and White were too far into development to shift to the upcoming console. IGN elaborates that "[S]ome games, most notably Pokémon Black & White, will gain some enhanced functionality when played on the new system. These cases should be considered extremely rare, however."
Pokémon Black and White were released in Japan on Sept. 18, 2010, and the Nintendo 3DS is due out there on the 25th of this month. Black and White will see their English-language debut in Europe on March 4 2011, with the 3DS being released on March 25, 2011. North American releases for Black and White and the 3DS will follow two days after each respective European launch.
