"Drought of hardcore games"? SPAC3 INVADERS EXTR3ME, The World Ends With You, FFTA2, N+, Kirby Super Star Ultra, Spore Creatures, FFIV, DQIV (and Izuna 2 and Pokémon Mystery Dungeon if you play Roguelikes)...yeah, none of those games are in any way hardcore whatsoever. Riiight.
I don't need a camera on my game system, and the R4 makes my DS a fully functional MP3 player anyway, so I don't really have any reason to want this device.
