I find it childish to believe that indie devs will kill anything but themselves. They exists because the revenues so far were low and big companies didn't bother. Indie devs are pioneers and pioneers inevitably disappear when the market matures.
Sure, smartphones market is increasing but that's mostly because they bring in new customers. It's stupid to think that someone who played on any gaming console will replace their beloved games with gimped down flash games.
"Games" on smartphones will ALWAYS remain at the stage they are now. Stupid flash games people play in buses when they want to put their brains on pause until they arrive to their destination. This "games" can't evolve more because they lack controls. Adding proper gaming controls to a smartphone is and will remain not possible. It would simply be too big and clumsy to use as a regular phone.
Anyone who plays games for the pleasure of it will most likely use their smartphones only to browse internet for more informations about their games console.
PS: also when you're gonna be on that train for a long time you will actually want to conserve your phone battery so you can actually use it as a phone :)
