It's being reported by Bleeding Cool that DC is launching a new Batman Beyond book, Batman Beyond: New-Year in April. While they may not always be reliable, they've included a pic from an upcoming comic announcing it.
I'm assuming that it will be spinning out of the Batman Beyond story from this week's Batman: Urban Legends #7 story.
