To be honest I don't see much changing really, except for those who have lost their jobs. The last game they developed in house was the latest Force Unleashed II, the vast majority of their games the past many years have been licensed games.
The LucasArts of old died a long time ago. Those who were fired will probably find jobs with the many companies that were licensed to develop games for LucasArts.
The only possible problem now is that all of the LucasArts IPs now rest with Disney.
1313 might still be salvageable if they get a third party developer to complete it.
All this "said". This is the end of an era and it shouldn't come as a surprise of how I feel about their adventure games
I also had great fun with a lot of their Star Wars games, but again that was the LucasArts from years back and not what was closed down.
