The new consoles have major functionality by being able to run in standby. If you're really that desperate to save power, just turn it off instead of putting it into standby.
Also, you guys need to stop being so OCD about something so minor. PS4 uses 5.5W in standby. That's $8.67/year if you pay $0.18/kWh. But what do you get for that money? Quick boot-up speeds, always updated files, saved states, etc.
Would you really rather wait longer to power up, then wait more to download that new 1.5GB patch, install it, and THEN finally be able to play just to save a few dollars a year?
