In various threads there is discussion going on about the upcoming 6.5 release.
Although it is good to read that Jetbrains will continue to add new features to IDEA I am also a bit hesitant to be enthusiastic about it.
There are still a LOT of outstanding bugs in 6.0 that affect usabillity. Things that really annoy people, sit in the way of being productive, things that still don't work after 2 point releases and things that are half finished. Just look at this forum as to what kind of things people are reporting or the outstanding bugs in JIRA.
I'm not sure whether I can affect Jetbrains roadmap at all of course but hopefully they will listen to a customer who says: please finish the 6.0 release first to get back that level of quality that the 4.x and 5.x released had instead of adding more NEW things to it.
