They would be mad not to do a special edition.
Considering how much money Sony are making with LBP DLC then im not going to be surprised to see GT5 possibly have options for personalisation or indeed new cars or extras from DLC.
If personalisation is not within GT5 as to the cars/livery editor etc then is it possible likely to see a GT area in Home? It wont shock me to see lots of GT clothing or content coming for that and to see if they do incorporate Home into the game like they once mentioned in an interview. Knowing PD though they talk in circles with little real information its all tid bits of possibilities, maybe's.
Dont forget "Car Clubs" was mentioned a long time ago as being a big part of GT5 this could also open up to personalisation or DLC stuff.
Being able to create your own specific club and race with other clubs, does this also mean you can have a virtual club pad in Home?
So much speculation but hey I guess we will soon find out. The "My Page" of the game is to allow many controls and inform you of race calender, club meets etc. IIRC they mentioned you can be a member of 5 clubs and create your own with upto 32 members per club. This is a nice feature if you wanted to enroll in a F40 club then from what they are saying you can and race other F40 clubs.
Im just looking forward to racing around the Top Gear track and being a sad little moron seeing if times in the game can match the real cars....
Now what about Top Gear DLC, can you put Jeremy or the guys in the car, that would be hilarious...
