If the Heat get a 6'11 or 7 foot center with toughness, a veteran point guard that can play defense, and a pure shooter, they will win the championship in 2012. They made it all the way to the finals with 3 solid players- Bosh, Wade, and James, and the rest of their team was average at best. Mike mIller was a huge disappointment, and they did not use Eddie House properly. Once they plug those holes they will win.
Lakers will be tough when they bring on Dwight Howard which is a must if they want to compete next year. Dallas gave everything they had this year and lucked out because the teams with more talent choked in the playoffs. As much as I hate to say it, the Heat will win next year just because they will load up more around the big 3 and anything less then winning it all will be another lost season.
