Well.
I'm a bit sad, but I'm fairly sure that the bot that we control isn't dead; it did seem a bit sad to part, but it didn't seem like it was sad to die or anything. In addition, there were other bodies, too (well, just one other, based on the ending). It didn't have an AI controlling it, and seemed to be off. Since it seemed so nonchalant, I must conclude that it can travel between bodies.
So perhaps in the sequel, he'll have a new body which we can have fun with!
