Yes, I know that nothing can replace powerful ObjC/Cocoa combo, but unfortunately I can't see myself harnessing such monster only to achieve fairly basic functionality mostly for my own needs
Also, if Apple is really going to include these Cocoa bridges in their newest OSX release, then don't you think they are pretty serious about unlocking new possibilities for developers?
Ruby or Python are really universal, they can be used for many many different purposes and I am simply excited thinking about having such languages (especially Python) on the list of officially supported Cocoa-able development tools
