Rise vs Mighty Maestro

The number of times I heard this conversation at a conference the other day was a lot.  It would be great if an Articulate staff could provide some intel if they have any.  We are looking at Mighty, but it is expensive and we are worried about the fact if you somehow have budget cuts and no longer can afford the extension then those blocks no longer work.  Would be nice for Articulate to just add these features.  My concern if for some reason you can't keep it then after your last zip file with the mighty blocks included are published those will play for he learner but then you couldn't update it anymore.  I saw some cool stuff someone had done on Linked in the other day.  I wouldn't have known it was RISE.
