What I'm curious about is the articles imply the heroes are stuck in Tatooine... So what about side missions? What about all those ally and hero missions set on other planets?
SPOILER for Hoth Campaign
The early missions of the Return to Hoth campaign have the heroes hide and barricade themselves in a remote safehouse to hide from the Imps blockading the planet. The next story mission involves the Imps breaching the barricades and assaulting the safehouse. There's a side mission window immedietely before that (IIRC my group took a stroll around Bestpin for that). So I don't think the developers are paying that much heed to stuff like that.
