For the Boston Celtics, the season ended bitterly in Miami against the eventual champion Heat, and according to a release from the Miami Sun Sentinel, that's where the 2012-2013 season will also begin.
Via the Sun Sentinel:
While the complete NBA schedule will not be released until later, the Sun Sentinel has learned that the Miami Heat will open the 2012-13 NBA regular season on Tuesday Oct. 30 at AmericanAirlines Arena against the Celtics.
The rivalry between the two teams has been among the most heated (no pun intended) in the league over the last two years and was only given more juice this off-season when sniper Ray Allen signed on with the Heat, spurning a Celtics offer that was rumored to be worth double what Miami could offer.
The Celtics have done well this off-season to replace him though, as they've added sixth man extraordinaire Jason Terry, Courtney Lee, and a re-signed Jeff Green to a bench that was desperately lacking quality last season. The team also re-signed Brandon Bass, Kevin Garnett and Chris Wilcox with the hope of overthrowing the defending champions.
