I doubt Sony will go this way, or if it does, I think it will change its mind later.
The whole "high price for blu-ray" thing theoretically makes business sense because the payoff is that Sony gets Blu-ray in people's homes. It's a big gamble, but if it works, it has huge benefits for Sony. With this idea, I don't think the payoff is that big. Sony would increase profits, but it doesn't have any major strategic value, and it only increases profits if they don't tick off too many customers. And that's the big problem: the public reaction to this idea is clearly very negative. The reaction to the PS3 hardware price is negative too, but there are those that don't care, and I'm sure there are even some who look forward to getting a "cheap" Blu-ray player.
