June's special marker cards have been officially revealed, featuring characters from Series 12: Soren, Lissa, Nowi, and Sigurd!
They've also announced the regularly scheduled shop pack battle tourneys for the launch of Series 13. It starts late next month but as it continues into July they'll begin distributing the next tourney promos, including the new Lyn.
I think this is probably the last update to expect before they'll begin introducing the new cards, unless they have a surprise for this weekend.
