A bad FF would affect mainly Japan sales, so it would be bad for Sony, as Japan is the market where take-off is happening most slowly. But I guess Sony is doing all it can to make sure SE does its best to make FF come off well, particularly for japanese tastes. From what we have seen so far, what could go wrong? Perhaps Uncanny Valley, but given that in Japan and Korea they like the current anthropomorphic robots, I presume they are immune.
