ReadyNas Ultra 4 Plus discontinued?

While I agree that it could just be that they have a disruption in the supply chain it is curious that every respectable eRetailer I looked at in the UK has it either marked as Discontinued or Out of Stock with no estimated resupply date.

Another thing that's also curious is that it's the same story for Ultra 2 Plus (as someone else already posted on this board) and I find it hard to believe that they suddenly have issues with both of these models.

To be honest it looks to me like they're doing the Apple thing (waiting until all the old stock is sold before announcing the replacement product), but only time will tell.

BTW, I am not interested in the extra "business" features offered by the Pro series and the price difference (in the UK) is significant - Ultra 4 Plus around £450, Pro 4 around £550. The annoying thing is that this state is pushing me to look at alternatives, i.e. other vendors even though I've been a happy ReadyNAS customer and I want to give them more business...
