Would it make sense for Sony to add an UHD drive in 12 months?

[ICStats]

I'd say they could possibly add it, but I'm not holding my breath.

With BR on PS3 at least there was an argument that games used BR and some needed more than DVD capacity, so BR wasn't just for playing movies. UHD BR would not be used for games in this generation, part because not needed, part because they must keep keep backwards compatibility with the original PS4/XB1.

If Sony wants to compete with Scorpio I think PS4 Plus Plus with another GPU would be the way to do it, and they have 1 year and know Microsoft's cards...
