Ladies and gentlemen, (re-)start your speculators. Nintendo has launched the teaser site for New Super Mario Bros., and there they've got the game pegged for a May 21 release. Once again, on a Sunday.
This once again fuels speculation that Nintendo intends to release the title, widely anticipated as one of the DS's killer titles, alongside the upcoming Nintendo DS lite. The reason: Nintendo almost never releases games on Sundays. The most notable time they did that in recent memory was when Super Mario 64 DS released alongside the original Nintendo DS.
So, once again, we'll simply have to see where this goes. At the very least, we do know that Nintendo currently intends to release at least the game on the 21st.
