lol, 11 Feb 2016because it their phone and OS. no fragmentation like androidFYI they are also doing for the PRIV via Google Play .
All their core apps are upgradable from Google Play which no other Android OEM is doing.
Others we have to wait for a system update.
It's nice how they can fix things via their app store.
Other manufactures need to learn from them.This bypass the networks\carriers .No need for them to do approvals which means no delays.
