No, it's precisely that survey, but it seems you haven't seen it either. It's not about indie developers' interest,
every attendant of this year's and last year's GDC - indie or otherwise - was asked which platform they plan on releasing their next game on, and these are the results.
But you're right about one thing, everyone is losing to mobile phone development, and web browsers are far ahead of all consoles, too. That's not so surprising, considering the sheer amount of trash that gets released on those platforms, but it's still significant from the business perspective, and all console makers would do well to address that. Sony's made some positive first steps, but we'll see how successful they'll be in the long run, and of course, Microsoft hasn't even announced their plans yet.
