In Ingress, they had similar partnerships with a few companies. Notably, the sponsored "portals" (the Ingress version of Poke Stops) were only additional locations to get items. They didn't award special items or do anything else differently (ZipCar and Jamba Juice had this agreement with Ingress). Ingress also had in-game items named after companies, but these items could drop from anywhere and were likely to be added to the game anyway. A couple examples of these are the SoftBank Ultra Link and the "MUFG" (Mitsubishi UFJ Financial Group) capsule. I think the only time they had a commercial partnership that gave someone in particular an edge was when they introduced Ultra Strike items, which could initially only be obtained on some Motorola-branded Android devices. These can now be obtained on any device, though. Given that it's the same team working on Pokemon Go, I think it's unlikely that they'll make things annoyingly intrusive or force you to go to specific Pokestops to get certain items.
