It needs to run on hopes and dreams.
In all seriousness, Sony is already fighting a major uphill battle now that titles like Kingdom Hearts and Metal Gear Solid are being released on 3DS as featured games instead of afterthoughts. They'll need to be able to appeal to female gamers for America / Europe, Monster Hunter for Japan, and a community based game ala Pokemon.
They also need their "it" that truly seperates the PSP2 from anything else that will already be out. Nintendo absolutely nailed their "it" factor with the glasses free 3D and they'll be able to coast on it even if something else is released with similar tech because they showed it first. The 3DS has great qualities for core games, casual games, and social games which could end up giving them that balance everyone has been seeking since the PS2.
