While Remote Play does seem like a very cool feature, many are still hazy on the details.
So, Sony Computer Entertainment Worldwide boss Shuhei Yoshida has given us some pertinent info via Twitter (and as summarized at DualShockers ).
When asked if the "Vita does any work at all" during the process of connecting to the PS4, Yoshida replied:
"Vita takes your input, receives and decodes video from PS4 very fast."
He also re-confirmed a fact we already knew, which is that Remote Play won't support titles that require special input devices, such as "dance games." Everything else works on a system level, which means that it doesn't require additional support from developers. Lastly, we learn that the Remote Play feature doesn't require an extra big memory card for the Vita, which is good news from a financial standpoint. Those cards are hardly cheap, as most of you are well aware.
I'm still not sure how well the controls will translate between PS4 and Vita for the same game, but I guess we'll find out. The question is whether or not this feature will increase popularity for Sony's new portable after the PS4 launches… I'd like to think it will but I kinda doubt it.
