Square Enix trademarks Lara Croft: Reflections, which definitely isn't single player DLC

Another map pack? Or a sequel?

Of note: Reflections is also the name of the Ubisoft studio that developed Driver: San Francisco. I thus deduce EITHER that Tanner will shortly be available as a playable character, with his own "reborn" narrative and horrendous QTE death scenes, OR that Tomb Raider multiplayer is about to get vehicle support. Or that Square Enix is working on a spin-off of some kind, possibly in the vein of Lara Croft and the Guardian of Light...

We already know that there won't be any single player DLC for the new Tomb Raider, and that there are currently no plans to release a sequel to Guardian of Light (which doesn't mean a sequel is entirely outside the bounds of possibility).

So, what could Reflections involve? The subtitle suggests another journey of self-discovery, as opposed to a game about defeating giants on horseback (see picture). Thanks to Siliconera for the tip-off.
