Having Kronos 2mins away from Earth at warp is, well, idiotic. Why bother with a neutral zone when both worlds are now next door to each other? Klingon surprise attack by its entire fleet based at Kronos would be straightforward. It should be days away at least. Preferably weeks! It contradicts everything in Star Trek so far.
I expect the next movie will get to the centre of the galaxy in say.... 10 minutes? Why not? Why not nip to the delta quadrant in 20 mins? If it serves the plot and the pacing then so be it.
I can only presume nuWarp is infact more like the hyperspace jump from BSG rather than old warp.
