Should we cry ? Or should you grab your N54-powered car while you can ?

The problem is that BMW's engine lineup is so confusing it hurts...
So the z4 sDrive 35is has a 335hp/340hp N54 engine and was just launched, and a 335is in on the way. Will the 335is have a further tuned N55 engine (to exceed the regular 300hp), or the already tuned N54 from the z4 35is ? God knows...I bet on the N54 to remain the more performance-oriented and to power the upcoming 335is/135is because otherwise they would have launched the Z4 sDrive 35is with the N55.
