I wasn't expecting more than one game from Sony for E3. Actually, we didn't even get that! Square Enix provided the only highlight for Vita owners with World of Final Fantasy, and its hardly an exclusive.
Enter the world of Grimoire, a kid-friendly version of the Final Fantasy universe, suggesting that grown up gaming is all but done on the format. Otherwise, there was one pic of a Vita throughout the whole show, and the well known indie and PS+ lists. They were only there as Sony's likely justification that the Vita is not "legacy".
