I think the joke is that he is playing Uncharted, which obviously borrows some of its ideas from Indiana Jones.
Seems so far the Vita, despite having some decent games at launch, is totally tanking in Japan. Meanwhile, the 3DS saw good sales number in Japan and the US, regardless of taking a year to actually get any titles for it worth buying. I spent the last year mocking my friend for spending over 200 dollars for a system so that he could play a game we beat together when we were when we were 12 years old (Ocarina of Time was the only 3DS game he found worth spending money on up until recently). It was even funnier when the price took a drastic drop less than a year out the door, and still prior to having any kind of a library.
But now, truth be told, I look at the new Resident Evil game (with its misspelled title) or think of how cool it would be to have Snake Eater on a handheld, and I kind of want one. Resident Evil: Revelations, looks like the first Resident Evil title they have gotten right in quite a while, finally going back to survival horror, rather than being just a clunky third person shooter (clunky controls, because clunky controls are scarier).
At this point I am kind of expecting the Vita to be a repeat of the PSPGo. Maybe I am wrong, but either way, I am pretty sure the Vita is not going to be the competition for the 3DS that Sony clearly hoped it would. For at least another generation (which come and go quick in the handheld world), I think Nintendo is going to remain king of the handheld consoles.
