Remember in Welsh (as in Welsh English), nawr/rŵan (now) can be used for the immediate future. It's perfectly fine to say Bydda i yna nawr (I'll be there now) when you mean "I'll be there in a minute", or Dw i'n dod rŵan! (I'm coming now!) meaning "I'll be there very soon, just not this very moment".
"now" is used in that sense in all types of English really, but then English - like other Germanic languages - doesn't have a true future tense; just "common ways of talking about the future". (no really! http://itre.cis.upenn.edu/~myl/languagelog/archives/005471.html)
Interesting to see nawr/rŵan gets used with the future in Welsh though, seeing as it does have a separate tense for it!
