Where has Redflow published the physical dimensions for the X10?...

Where has Redflow published the physical dimensions for the X10? I looked, and couldn’t find anything. Without that information, your pretty picture that you say shows a significant reduction in size is… wishful thinking at best.

My suspicion is that the physical dimensions will be proportional to the increased storage capacity - eg, a fourfold increase in capacity implies a doubling in two dimensions. I very much doubt that you’ll see that much of a reduction in size for a given capacity. 10-20%, absolute maximum, would be my initial guess.
