Alanabit, I agree obviously with the context assertion and that's why I meant in the context of 'gleich geht's los', gleich can only mean now or 'soon'. I lived in Rothenburg ob der Tauber for quite a while and learned 'Rothaburgerisch' from the Oma in the youth hostel, where I worked. If one was asked to do something and you wanted to prevaricate, you could say 'gleich, gleich!' meaning 'OK, I'll do it in a minute!'
