Announced earlier today, NBA 2K12's Legends Showcase will drop 45 new stories players into 2K Sports' hit b-ball title. You can take a look at how the new graphical style looks in the trailer and screens posted above. Legends Showcase will also include several new modes and mini-games like H-O-R-S-E and 21. You'll also be able to play match types like 2-on-2 Teammate Challenge and 3-on-3 Era Challenge, highlighting specific tandems.
2K Sports also says you'll be able to mix and match current players and old-school Legends and you'll be able to use your My Player created athlete in these modes as well. Finally, the Legends Showcase will introduce up Classic Quick Match, a new mode that lets you use the NBA's Greatest teams in regular simulation face-offs in the main game's online portion. When it, y'know, starts working.
