Two questions:
1) I'm assuming the near 1 to 1 experience is when you're near your ps4 (i.e., in your house with the ps4 in the living room) as opposed to being outside or farther away?
2) If I'm going to DC and live in NY and want to remote play, I need to leave my ps4 on in my house in NY and then connect via wifi to ______ to play? If so, issue with power being on while not being home and is the experience going to be worth it assuming the wifi is good?
#1 at home it will be very very close to 1:1 experience.
#2 Whenever you shut down PS4, it goes in standby state. There is no "full shutdown". In that standby state console uses minimal ammount of power, it maintains connection with PSN so that you can command it via smarpthone to dowload games, patches are automatic, and new firmwares.
Additionaly, whenever you are
away from home, if your Vita is synced to your console [
both need to have same account, both to be "activated" in system settings], then you can remotely turn on your PS4 with Remote Play app on Vita. Quality of the video will depent on UPLOAD SPEED of your PS4 [via lan cable or WiFi to the router], ping between PS4 and you, quality of the WiFi router where you are, and download speed of router where you are.
After launch they will add support for game hibernation. You can start your game in NY, shut down console, get to DC and continue playing where you have left off. They have shown that in "A day with Playstation" video during TGS.
