We’ll hold our hands up. We don’t know. It could be, or it could be rejected concepts from Uncharted 2 (or good fan-made images). The styling is certainly pretty similar, with the Hindu God Vishnu appearing and Uncharted 2’s Buddhist, North Indian/Nepal/Tibet scenery putting it in the same geographical region as the second game. It’s not quite in-keeping with one or two other rumours we’ve heard about the third game’s setting either but you never know.
We got a tip from icuyesido sending us to this Portuguese language site which seems to be claiming that they are legitimate (my Portuguese is a little enferrujado) but we can’t confrim them and we doubt that anyone from Naughty Dog or Sony will either. We’re advising a healthy dose of caution before everyone starts getting all excited. Still, worth a little look, right?
Update: There you go, looks like this rumour is probably the result of a very talented guy called Albee Ng and some quite enthusiastic gun jumping by the aforementioned Portuguese blog (and Amazon.fr for that matter). Great work Albee, if you’re reading!
