Dynamic theme costs outweigh revenue
Well Q-Games, who are behind the PixelJunk Monsters theme and the sparkles on the new XMB, have replied to the concerns by gamers by saying that their costs for making the themes are a lot higher than the revenue they make in return:
Remember that we’ll be lucky to sell even a few thousand themes, and so the cost of developing the theme (3-4 weeks of coder/artist time, checking, testing, etc.) will still far exceed any money we make from it.
Of course you shouldn’t forget that the themes are a great way to promote games, and so the profit they make from those extra sales should make it worth while for them in the end- after all they wouldn’t be making the themes if there is no financial incentive.
We hope that after the hype behind the new themes has died, that prices will naturally fall. Reducing the prices to around half of what they are now would make them have a lot more value for your money.
We are yet to see how much SCEE will charge for the themes since none have been released in Europe yet.
