I just found a picture of the new Savic Hamster Plaza cage on their 2016-17 catalogue! It's available from September onwards apparently.
It's 100cm x 50cm x 50cm - has a big front opening door and base looks quite deep. Bar spacing 9.5mm
It's on page 117 of the catalogue

It's a bit taller than they discussed at 50cm tall, but I'd originally said taller with a deep base for more substrate would be good! So it's probably about the same height as the Alexander cage - maybe a cm or two more. Wish I knew how deep the base was. It would be good with lots of substrate and an extra platform.
Love the big front door
Plus no door on top so you could hang as much as you want from the roof.
Didn't see a price on there.
