It depends on the confluence of several semi-independent streams.

First, the rails-core team seems to have one person working on 1.9  
compatibility.

Second, ruby1.9 itself needs to stabilize a bit before it’s ready for  
serious production work. Matz’s team switched the version number from  
the hoped for 1.9.1 to 1.9.0 shortly before the Christmas release and  
indicated that 1.9 shouldn’t be considered stable. It will probably  
be a few more months before they release a 1.9.1 version which would  
be the first ‘stable’ release. Until then any 1.9 stuff rails or not  
should probably be considered experimental.

And then there’s the question of 1.9 compatibility changes to all the  
third-party plugins and gems which are used in the many rails  
applications.

It’s all coming, no doubt, but just when is hard to predict.

Thank you for answering.  
I was eager to know cause I’ve read wonders about 1.9 performances and  
was wondering how that would impact on my rails app performance…
