It looks like indies are going to get a lot of chances on consoles. Sony will also be offering Unity support, like Xb1, but it doesn't sound like it will be their central development platform for indies.
It's a start, but the platform is still tightly locked down. It's not like any game dev can make and publish apps. Like Xbone, you still have to go through the proper channels. IMO most indie devs are still better off targeting open markets like mobiles and PCs. Still plenty of money there and the rules are not so harsh.
Yes but it's a step up from what Sony used to do.
