	That probably isn't what you're asking for, but my vote would go to 
"both". In different colors/tones, of course (for example, highlight in 
blue the instruction that is about to be executed, and in grey the one 
that has just been).
	Lacking that, highlighting the instruction about to be executed makes 
more sense to me.
