I think Nintendo were actually bigger than Toyota at some point during the Wii/DS era, let's see how things look down the line, they need sustainable growth, not huge spikes in either direction.
That said; I'm confident that they're out of the woods and will do well in the next 4-5 years, they seem to have accepted that they need to break norm and tradition to start earning revenue again, even if their efforts with the NX should fail or at least fail to deliver what they're hoping for, they now have a potential market segment to keep the cash flowing and investors happy.
Let's hope it sticks!
