On one hand, I can understand why their focus was strongly on the PS4. On the other hand, damn guys, you've got a handheld, you know. I guess there isn't much they could really announce though. For the most part, Vita game announcements just kinda happen when they happen. We already know about just about all of the major releases planned for the next few months, and I'm sure developers will announce more for the Vita as the months roll on.
Anyways, my impressions of E3 up to this point:
Okay
Suck
Suck
Decent
As predicted, E3 has brought just about nothing really great to the table. Let's face it all, it's kind of useless these days. Also, anybody expecting Nintendo to blow Sony and Microsoft out of the water: lol. I'm ridiculously positive that Nintendo will show nothing of surprise in their Direct. We all know exactly what Nintendo has to offer year after year after year. The offerings don't change. At all. Ever.
