This is somthing I posted in another thread but it's aplicable to this one as well so here you go, something to think about!
Has everyone missed a problem?
What problem I hear you cry, weeeeeeeell This may settled the speculation, or make it more heated LOL
Lets first look at an example, going back to the 360 (steady on) when a car pack was made available where you could buy additional car a problem arose, if your playing online and you hadn't bought the additional cars and players in the race had the new cars how could you see them? Not having downloaded the new cars there was no way of displaying them on the screens of players without them. So what they did after different approaches (more on these in a second) is that everyone got an update, in this update were the new cars, you couldn't use them unless you payed for them of course but everyone physically had them.
So this raises the question for a few people, JPN version owners especially! If the online section is going to run globally and not regionally (Lets hope not) Then EVERY version will need ALL the cars to work! Now sure the cars could be but onto all versions and just certain ones be locked for certain regions, but this makes absolutely no sense! Even if you have to pay for additional cars to be "unlocked" this would be ok but I doubt PD would do this for fear of alienating there home market!
Anyway a quick look at the alternatives which other games when faced with this problem tried unsuccessfully, 2 main ones spring to mind, 1 was the simple system of people without certain downloadable content wern't able to play in rooms where the new content was being used, this was soon dropped as it quickly split the gaming communities into have and have nots and people soon got annoyed and moved on to other games. The 2nd system was to have a "generic" car which everyone had, so instead of people without exclusive content not being able to see cars they don't have they see the "generic" car in it's place. This last system works but took away the show off appeal of people wanting to show "new" cars in online races so less people bothered buying them (Yeah we are that shallow LOL)
So PD and Sony are not stupid and have the advantage off seeing how people got around this problem in the past, and I'm sure all versions will eventually have ALL the cars within a space of time, Lets just hope the system is in place before the EU and US versions are released so the JPN guys out there don't experience restrictions online!
Again this was for another thread so some points have already been mentioned on here.
