Will There Be a Slacker 3 Game?

No official announcement or hints for Slacker 3.

• Original Slacker (1999) by LucasArts.
• Sequel Slackerz (2000) was lighter, less acclaimed.
• No news since; IP owned by Disney (via LucasArts).

Classic revivals happen — watch Disney/LucasArts channels. But currently: no plans.
