When I started playing X in mid December, the fletchling that Serena had to catch for the tutorial was shiny and I totally freaked out.
Unfortunately, I was too late to take a photo of it since the whole tutorial is automatic. I mean, it doesn't stop and doesn't require that I press A button to continue.
Fortunately, it wasn't my first shiny. I play since the european release of Red and Blue and I 've seen/caught several shiny mons during the 16 years I play the games.
Has it happened to any of you in X or Y?
