Sony's PlayStation 4 reveal is lined up for February 20, and Evolution Software is teasing its own reveal on the same date.
Over the weekend, Evolution Studios game director Paul Rustchynsky Tweeted: "10 Days!"
Evolution is the studio behind Sony's popular off-road racing franchise Motorstorm, which debuted at the launch of the PS3. It's been a while since Motorstorm Apocalypse, which hit stores in March 2011, so it's possible the studio's new title would form part of the PS4's launch line-up.
Adding some clout to speculation is the LinkedIn profile of Evolution design director Simon Barlow, which states he is working on a "AAA first-party exclusive" which began development in March 2011.
It's now only nine days until Sony's February 20 event.
