"Tunesy...were you going to take an upgrade path? Because remember the carrara beta deal. You did not get the free 5 when you bought 4 if it was an an upgrade or companion. So unless you were going to buy it at full price ...may not apply. Either way I would ask someone."

For my particular situation Eovia's press release #54 quoted earlier in this thread answers the question.  I can't speak for the other promotional iterations though.
