Bethesda Games Studios director Todd Howard's confirmed the developer has a new project in development.
Speaking during a panel about creating blockbuster titles with RAGE producer Tim Willits and Respawn Entertainment's Vince Zampella and Jason West, Howard confirmed the project's been in development for two years.
He wouldn't confirm any more details then that.
It's been highly speculated the title Bethesda's developing internally is a new Elder Scrolls title, one which may be an MMO - neither of which have been confirmed.
