This is what I found on e-on software site..................

{If you buy Vue 5 Esprit now, you will receive your free upgrade to Vue 6 Esprit when it is released (download version). }

So if you buy Vue 5 now you'll get a free upgrade and if you were a loyal costumer and brought Vue 5 before now you get nothing for supporting them in the past.Now am I correct in that assumption:)
