@Johnnypenso makes a good point about network stability. Wireless connections are more common on consoles, there are more casual players squeaking by on shoddy internet service, and unless the developer/publisher (or console manufacturer) provides dedicated servers, it's all P2P. If we're basing this on Darin's comment in the ISR video, he specifically referred to online racing, not a singleplayer limit.
It's "okay" for PC gamers to be responsible for their connection quality and deal with complications, but for a "polished" console experience it would be undesirable for lobbies to frequently fall apart once they grow beyond a certain point.
