The Koch Media tweet is legit, they distribute most part of Eidos and Square-Enix games in Spain.
But they deleted the screenshot tweet and other that says something like "all that we know is that they will be released in digital format". I've got screenshots of both.
We all know that Koch, given digital releases of Vita titles are mandated.
Seems weird they would cite cart size for not bundling the games on Vita together if they're not putting them on carts at all.
In theory, X/X-2 would come together digitally on Vita as well if there's no physical release at all.
