Interesting to note that they have announced version 6.0 of IQ, and at the same time announced that it will be EOL from the middle of next year. It will be replaced by a brand new product Visual Workflow Manager, and there will not be an upgrade path. All configs will have to be done from scratch again, with the exception of a couple of items (MoH, prompts, conditions, all of which are external files anyway).
VWM looks like it will be released in Q4 this year.
