I wouldn't worry about it.
It's unlikely, IMHO, that 3D is going to succeed in the home. Bandwidth concerns, sure. Low demand will certainly keep it almost completely off cable and satellite. And limited infrastructure and FAPs will certainly keep it to a minimum on the internet for many years to come.
So IF 3D has any chance of succeeding in the home, it will be originally thru Blu-ray. And that will require up front investments, carrying it at a loss for years, as the tiny number of owners of 3D HDTVs & players, and the tiny number of 3D titles, grows. But Sony has done this before.
I smell another Smell-O-Vision.
