As is the case with every version, anyone who knows is legally bound not to say when or what. Neither would we want to - I think the big gorilla has pinched enough of our features, let's not give them a head start.
My layman/alpha/beta tester insight on the process is that Graphisoft obviously don't sit around until 'that time of year' and then decide what they'll add to the new version. To a large extent development is roadmapped years in advance. As with any software development, the alpha version and pre-alpha projects are created and tested way ahead of their final release date, so that the concepts can be set, and the main code can be edited, tested, bug fixed, etc, etc.
As a tester it's not exactly like we can influence the front end development (although we try bloody hard!), we mostly help reduce the amount of bugs in the code that has already been edited towards the end. We do this mainly for the love of the program, and if we put in a big individual effort, perhaps an award/reward. We certainly don't get paid.
Rest assured that
extremely
smart people are looking after the development of the program, and they are
well
aware of the outstanding wishes and bugs. And they
are
listening. All I can say about the next version, from what I've seen, is that I'm very excited about some of the long-standing wishes that will be included.
Take a look at the past
release schedule and you can do you rmath on when the next version may come out. Good things come to those who wait (and pay).
Cheers,
