[development] also waiting for 6.0 RC to roll out?

Hi to everyone! I know it is annoying to get this kind of questions to developers, but I am kind of a desperate to START a new multi-lingual, multi-template site with at least Drupal 6.0rc... If I do it now with 5.3 and then switch, I will confuse both editors and designers with change of interface and features in first weeks of use :-( Any ideas when could we see first RC to role out? best wishes - Zeljko
