Head of Xbox Phil Spencer hinted yet again at the announcement of a new Battletoads during today's Windows 10 event. Spencer, known for wearing t-shirts promoting upcoming Xbox games, sported a green tee with a large Battletoads logo, though he never mentioned the game by name. Microsoft filed for the Battletoads trademark in November of last year.
The original Battletoads, created by Rare, was a beat 'em up released on the Nintendo Entertainment System in 1991. Microsoft acquired Rare in 2003, along with many of its properties. Spencer himself has mentioned his fandom for the franchise, though a new Battletoads hasn't been released in over two decades.
