From the article:

“It was pretty much done, it was in final [quality assurance testing],” Free Radical founder and former studio director Steve Ellis told GamesIndustry.biz in 2012. “It had been in final QA for half of 2008, it was just being fixed for release. LucasArts’ opinion is that when you launch a game you have to spend big on the marketing, and they’re right. But at that time they were, for whatever reason, unable to commit to spending big. They effectively canned a game that was finished.”

Still better than the new EA ones which aren’t finished and aren’t playable.
