The EU is a FANTASTIC revenue source with a pre-built fan base. Disney won't throw that way.
Of course they will.
The prequel trilogy was unmitigated trash, yet it still raked in money. Hardcore Star Wars fans have eaten up eighteen-odd clones of the Emperor, Darth Maul not actually dying when clearly killed by Obi-Wan, Boba Fett surviving the sarlacc, etc. This is a fanbase that will buy anything, no matter how absurd, as long as it involves their favorite whatever.
