This is what I wrote Denis, yes. 
But there is no Team Decision on this yet. I will keep you informed...
I vote "yes" because there's been far too few updates in 4.x. The last update was over a year ago now. So for time passed, amount of updates in 4.x that have been rolled out & for the inconvenience of not getting an update in over a year my vote is a great big YES to giving for free to 4.x license holders.
Besides, with a bit of tweaking, you can probably get it on Steam. Also with a bit of marketing I'm sure you can get more people interested in the engine too, especially if you can get Simon or seek out a couple or so more talented programmers to add to the dev team for rolling out some periodically consistent bug updates - say at least 1 per month, regardless of how minor it is, as it's better than no update at all.
