Now the event is over, Tokyo Game Show floor footage, gameplay videos and other content is rolling across the Internet, with lots of varying quality clips of the Vita/PS4 titles to come.
Overall it was definitely a show that breathed plenty of new life into the Vita, assuming everyone still reading this blog is into their Japanese games and regularly prays at the altar of NIS, Bandai, Koei and Atlus for western translations.
I'll add more videos as I find them!
Dragon Quest Builders (starts around 15 minute mark)
Gundam Extreme Force
Hatsune Miku Diva X
