New Tomb Raider game to be called 'Shadow of the Tomb Raider'

It looks like someone was smart enough to go out in public and put on a page that possibly leaks the next name for Tomb Raider, ‘Shadow of the Tomb Raider’ on their laptop. Redditor, Tripleh280, was traveling on a crowded subway in Montreal, Canada and caught the name on camera:

If you zoom in just a little bit you can make out the name ‘Shade of the Tomb Raider’ and this could just be a possible code name by Square Enix who have yet to say anything about this.

“The page he was on talked about visuals,” Tripleh280 Kotaku. “I’m from Montreal, QC. I was going downtown for work and I took a quick snap. I really would love to say more but other than the title, the rest was blurry from where I was.”

What are your thoughts on all of this? Is it all just a code name, completely fake, or an early leak?
