Is it possible to run Ruby on Rails with Ruby 1.9x?
Browsing the web says that Rails is not compatible with Ruby 1.9 but I would like to know if it's always the case?
And how long should we wait to see a Rails version working with Ruby 1.9? Is it work in progress? In dev stage?
Yes, the latest Rails works fully with Ruby 1.9.1.
Issues you have will be around gems/plugins that might not be compatible yet. But more and more of the popular gems/plugins are now working with 1.9. (As pointed out in Rahul's link.) See isitRuby19.com for compatibility info.
The other aspect is that if you're developing on Windows, there isn't a one-click installer for Ruby 1.9 yet, so getting set up locally might be more of a pain than it's worth.
Hope this helps:
Ok, I found this link:

Indeed, rails 2.3 works with ruby 1.9. That's cool!
yes, but you are gonna have a lo of troubles with the plugins
