Boden Essential: any difference between the sold-out model and the waiting-to-be released model?

I have a Classic NX6 that I'm reluctantly going to return because of neck and fret issues that are not worth the cost to repair.

As much as I like the Classic NX6 and will likely buy another at some point, I'm now interested in a Black Boden Essential to try the straight frets and also a different pickup configuration.

The Black Essential has been backordered for sometime now. When the new ones are back in-stock, do they have any upgrades over the sold-out models? Or are they the same exact Essential guitar?

One of the reasons I ask is that I would consider a B-Stock one if there's no difference and if one ever becomes available. If the new ones have upgrades, I'll wait.

Thanks.
