"Prices will go up: they need to"
The assumption seems to be that if they slap an extra $5-10 on the price that they'll still get the same base of people buying games. I don't think they will.
Taking the Japan view on things , top line games are coming out around 8100 yen , but mainly others hit at around 6800. The thing is , the main reason (at least IMO) that the japanese market is shrinking is because there are so many other things to spend your cash on (DVDs being one).
A price hike of 500 yen or so isn't going to help this situation.
There is two schools on thought :
1 - you up prices and hope you keep the same buyer base.
2 - you lower prices and hope to increase your buyer base.
I'd like to see EA take the industry by the balls and go for the 2nd approach, because it would put the shits up everyone else and everyone would have to follow suit.
Also, from my IP copyright job days, a new format also carries a "New format tax" (at least in the UK) for a couple of years. I assume that Blu-ray/Whatever MS uses will also be subject to this tax? Anyone know if this tax is the same in the US/JPN?
That could push the prices up by a good few dollars on it's own.
