Well...yes. The Indie scene has advanced WAY beyond its roots. I mean, there's still your retro platformers and stuff and that's all good. But even in the platformer scene you see increases in production value with things like Dust an Elysian Tale, Ori and the Blind Forest, and Shantae: 1/2 Genie Hero. And of course Ubisoft dabbled in this with games like Child of Light and Valiant Hearts. But you also have bigger, more ambitious indie projects actually managing to get somewhere. Shin'en of course have produced some impressive pieces, FAST Racing Neo being it.
In the indie side of this re-emergence, the real motivating factors are 1) the growing availability of highly intuitive tools like Unreal Engine 4 and Blender, 2) connectivity allowing teams to meet and assemble from across the world and also for teams to help each other with tutorials and such, 3) believe it or not, the economic issues that likely motivated many companies - including game companies - to "get lean" and in the case of game titles focus more and more on big budget "guaranteed" earners. So now you have people interested in doing smaller or more personal projects and big companies said "no" and over time, that group has decided to do it themselves. Crowd funding and the growing interest of independent investors in the game industry have no doubt also helped as developers are no longer forced to deal with big publishers.
And the success of indies has helped motivate big companies to dabble back in this field again, since they now have proof such projects can be winners.
