So here's
my theory for what Gran Turismo Sport may turn out to be like, based on the three modes as mentioned in this article, courtesy of Ben Rogue

Campaign Mode - A single player experience where you as a driver will rise through the ranks of multiple tiers of motorsport. Starting off with road cars and moving up to GT3 and Prototype race cars. Other categories such as Kart racing, NASCAR and Rally racing may also feature.
The game may introduce a system that is similar to Project Cars. So rather than buying cars from dealerships, you gain access to them through team contracts. However, they may do something completely different. Perhaps we will have to fund our own team, and part of that process is buying and customizing cars to compete in a range of races. For example, there may be a 'Modern Hyper Car Championship'. We could go to the dealer and buy ourselves the newly introduced Lamborghini Veneno and modify it within regulation to compete. These single player championships may feature built in drivers and manufacturers titles, each with their own in game prizes, such as new cars or credit bonuses.
The campaign mode races may serve as a sort of training programme for the FIA online races, pitching you against AI drivers of varying difficulty levels, whilst also allowing you to get to grips with mechanics such as race flags, pit stops and mechanical damage.
In addition, The Campaign Mode may also feature traditional multiplayer sessions, where we can bring in our own cars and organize races to our preference, as we could in the multiplayer of GT5 and GT6. Other features may include the return of photo mode and photo travel, GT Auto for vehicle customization and maintenance and so on.
In other words, the Campaign may simply be a re-branded 'GT Mode'. The reason for its re-branding might be to make it more recognizable for newcomers to the series.
Sport Mode - The FIA online portion of the game, featuring both the Nations and Manufacturers cups. These FIA recognized online races may have players drive non-modified cars under strict regulations to encourage driving skill over vehicle performance. How these races will be organised exactly is something we don't really know yet. But we can probably establish that the gains from the 'Campaign Mode' such as the cars we own/teams we are part of will be irrelevant to the FIA championships. With this said, players should simply have full access to the Sport Mode, regardless of their progress in the Campaign mode.
Arcade Mode - Well, this mode is fairly self-explanatory. A selection of cars and tracks which the player has full access to from the very start, with the intent of getting the player used to the games controls and mechanics, before jumping into the campaign mode or the online races. Arcade Mode may also provide traditional split screen gameplay.
This is just a theory, so my predictions might be well off, but this kind of speculation will help pass the time at least
