Haswell MacMini should I wait for it?


I've been developing for iOS with a 2012 Air. Thou I have no complains and it is pretty much the best laptop I've ever own, building times are getting a bit tedious, the limited HD space is also not helping.

Long story short: I want to buy the Core i7 mini (plenty of monitors and peripherals around), For you guys familiar with Apple Cycles: Should I wait for an Update? Does it usually take them long to update the Mini?

I know its speculation but I was a .Net developer till I had to switch to iOS, so I haven't been following Apple for long.
