Well...
I know speculating makes no sense, but as I'm probably not going to upgrade, I'm more interested in the name, than the feature set.
The major question will be, what happens after 10.9. Does apple have something up it's sleeve (for about 12-18 months hence), which justifies a major increment (whether it's Mac OS X 11.0 or Mac OS XI ), or will apple just go for Mac OS X 10.10 ???
If they go for 11.x then they're out of the conundrum of thinking up new cat names and can go for whatever (dogs, planets, constellations etc.). If so, then 10.9 will be the "final cat", and I personally hope for "Lynx" (reason being that that's the only big cat we have here in northern Europe and have been felt left out thus far
)
