I'm really trying to not give too much away as I feel that would be a breach of the NDA I have signed
However; One thing that I will say.
When the new Hubs come up for sale (Don't ask me when because I don't know)
I see no reason to change mine. (except the new one's prettier) 
Bear in Mind that Bruce has already said that the current spec (mem, cpu etc) is not in the least 'stretched' unless there is a loop or something consuming resources
(And yes I have seen it and had a 'play')
