IGN has posted a preview of Bustin' Out on the consoles a few days ago. Besides discussing Create A Sim, the campaign mode and some technical things, they also discuss the special features of each version:

"PS2, GameCube and Xbox owners are each getting some unique features. The option for a 720p display will be available for the Xbox. PS2 owners will get an online option where they can host a "Sims Weekend" event where everything that you've unlocked in your game will be open for you and other players to enjoy online. Players come over to your town and trade items and other goodies. It's basically a cool interactive way to cheat and get items that you otherwise wouldn't have unlocked. Think Animal Crossing but without the bizarre looking critters and leaves. The connectivity between GameCube and GBA allows you to buy an arcade cabinet in the console game that your sim can walk up to and "play." When he or she does, the GBA game then becomes a minigame player that lets you run through up to eight mini games if you have the GBA version of Bustin Out and 4 if don't have the GBA cartridge. The money you earn in your minigame session will be transferred to your GameCube character's account. While you're playing your minigame on GBA, your GameCube sim is standing at the arcade doing his or her "videogaming" animation."

There are many comparisons to the PC version of the game, but less to the console version that's been out for a while too. Besides this preview on this page, there are also two new pieces of art in the Bustin' Out GBA section at IGN. You can see them right here.
