Is the PlayStation 3 Dangerous for Small Companies to Develop for?

From the article:

So is it dangerous for smaller studios to develop big budget titles for the PS3? If making a single PS3 game has the risk of bankrupting your company, surely that will make the idea less appealing. It's unlikely that developing a game for the PS3 was the sole cause for the two studio's untimely demise -- but there is no denying that Free Radical and Factor 5 both released just one game this generation, and now they're both out of business. Was this just the sign of two small studios not being able to run with the big dogs, or is this a sign that developing for the PlayStation 3 is the industry equivelent of Russian Roulette?
