The problem is that the anti-trust authorities have been very lazy and slow when it comes to dealing with monopolies lately. When it came to Standard Oil and AT&T, the authorities acted decisively and split the companies up. The baby Bells and SOs became the the vibrant and competitive oil companies and telecom companies we know today. The problem is that with globalisation, there is a degree of protectionism granted by anti-trust authorities to companies from their own countries. For example Lockheed and Boeing are the only two aerospace companies left in the US and with the exit of Lockheed from civil aviation and McDonald Douglas taken over by Boeing, the US government is going to find it difficult to get a competitive tender in future for defence jobs. If they want a tanker or EW platform, they only have Boeing to go to. If they want a fighter, they have to go to Lockheed since with the loss of the F22 and JSF by Boeing, means Boeing is effectively out of the fighter business for future fighters. The vibrant, inventive US aerospace industry of the past is gone for ever. In US and Europe - anti-trust authorities don't want to break up monopolies up because they feel bigger companies will be able to compete better in the global market. That is why Microsoft has been treated very differently from SO or AT&T.
What I mean by laws of economics, is that in a competitive market, you can't charge your customers extortionate prices, threaten your customers with price hikes or withdraw your product if they do business with a competitor, or dictate draconian terms and expect them to accept. In a competive market, you cannot hike up the price in one sector and indefinitely run at a loss in another. If you do this in a competitive market environment, the laws of free market economics (as promoted by Adam Smith) will mean you go out of business because your customers will walk away.
I understand what you meant now, I'm very much in agreement with what you wrote but I just have a lot more belief in the regulators, especially the trigger-happy EU comissioners whose propensity to get involved knows no bounds.
I would say having a lock on all the important japanese franchises is excluding others. A real monopoly does not have to cut prices because there is no true alternative. A real monopoly can charge what they want because there is not viable competition. If you want to play the biggest japanese titles you have to buy a PS3 no if ands or buts. Because of this sony can get away with charging an outragous price for thier product. They can use gamers to push a stupid movie format because of they have excluded others. You can bet your ass if sony was in MS or ninendos position coming off of last generation they would of not charge a kings ransom to push a movie format.
Sony might not have a complete monopoly right now but they are inches away from it. Nintendo has already given up directly competing with sony they are going to try and make it as a niche player. If the 360 fails like the xbox before it MS will be gone also leaving just sony and a niche player in nintendo. Times are interesting but also damn scary.
Sony does not have a lock on the important Japanese franchises. Just how important these titles are in Japan is also up for debate, FF seems to be a 2m-3m seller at most, with >70% of sales racking up in the first days of release alone. DQ is still powerful but Sony has not got that under it's belt at all, Square often releases it on the console with the most units sold in Japan and well that may well be Wii. DQ isn't a game concerned with visual presentation and would not suffer, from the point of view of its audience, if it were on Wii - where as the rationale for no FF on Wii is the direct opposite.
MGS, DMC, RR, Tekken, VF, Monster Hunter are all easily capable of going multiplatform and they might well do if PS3 does poorly while PES is already multiplatform. This only leaves Sony's first party (Gran Turismo) and Nintendo franchises. There is no lockout in Japan. The appearance of a Sony lockout is only due to the rejection of the 360 by the Japanese consumer. For Konami, Square and Namco that plays a large part in dictating their policy.
