While it may be true that the old processor costs Apple more to build than the new models I strongly believe that they didn't want to test the device again.
The device worked as it is and it will work in the next year as it worked so why should we change it? No costs on this side to find.
We can argue about costs and which of them would be higher but either way I think they choose the way which fits Apple best.
Apple wants to mess with new stuff and not with old already gone low-end model phones.
I don't know how non-tech-users see the nexus. I never seen one have it. I don't know why but it seem that the majority was bought by techies compared to a 3 GS which was bought from all kind of people including a lot of females which argue "I don't need the latest stuff".
