Of course, I'll be glad to make sure Sony sees the list every so often. Can't promise that they will always change prices, of course, but it's obviously is good to have that info available for them. Hopefully, as you suggest, they are looking at long term solutions to the pricing anomalies. Depending on the information and people that are available, plus maybe other circumstances like if there is any interaction with publishers (although Jane was suggesting they might not need to be in the loop), it might either be easy or hard to fix.
Regardless of whether they can continue to move prices, it'still pretty amazing that a company like Sony would even show this kind of interest in issues like this! I think the desire to get things right is half the battle.
