Currently there are four ongoing SWs comics Knights of the Old Republic (Taking place 4000 yeas before the events of the movie) Dark Times, (Shortly after Revenge of the Sith in the Purge Era), Rebellion, (The time period after Yavin during the Galactic Civil War), and Legacy which takes place 140 years after the movies with Luke's ancestor Cade Skywalker.
How does a cross over work when non of the comics take place in the same time period? Your guess is as good as mine. Evidently it will run through 4 issues of KOTOR, 2 of DT, 2 of Rebellion, and 4 of Legacy.
Heres the closest I can find to a plot summary
"
When a terrible vision reaching more than 4,000 years into the future alerts the secret Jedi Covenant to the importance of Taris, they activate an operative already on this planet overrun by Mandalorians. There, in the deadly Undercity, a monstrous, ancient threat is unleashed that plunges Zayne Carrick, the Padawan accused of killing his fellow students, into an adventure which will eventually span four thousand years and involve Darth Vader, Luke Skywalker, and the principals of the Legacy series."

I have no idea what is going on, but I am all tingly inside. It will either be really cool or completly terrible.
Heres hoping for the former

They had to do something to give him back all the cool he lost in the prequels, right?

You could pick up the Rebellion and Dark Times trades to get he back story on them. They are My Brother, My Enemy, and Path to Nowhere.
