Ultra 4+ vs Pro 4 / Any new products on the horizon?

Hello I am currently running an out of warrantee NV+ and am looking to upgrade and have two questions. 1) Can anyone highlight the differences between the Ultra 4+ and the Pro 4 - they seem very similar looking down the spec tables? 2) I realise that Netgear don't publish product roadmaps for new products but does anyone have any info on new versions of the Ultra 4+ or Pro 4? I am very very reluctant to purchase a product that was first released in July 2010 in the case of the Ultra 4? Surly these units are due a refresh? Any thoughts or advise would be very welcome. I am also looking at a Synology DS412+ as a similarly specced 4 bay prosumer unit. Cheers JEBR
