CPM SPY 27
Let's make it simple. Does it look like SPY 27 will be easier to sharpen than S30V?
SCARAMOUCHE!

I would say yes but only marginally. It will probably fall in between S30V/S35VN and VG10.
I would guess that XHP or CPM154 will sharpen up similar to SPY27.

DBH does a good job talk about what the steel could be in this Instagram post.
Re: CPM SPY 27
Any idea when the first release will be?

I’m waiting to hear what hardness they plan on treating it at... tempted to pre order but I’d be heartbroken if it’s 58hrc

Ease of sharpening is a more complicated matter than it may seem. You also have to consider how WELL a steel sharpens.
The softer a steel is, and the lower the carbide volume will dictate how easy it is to grind, but those same qualities can also be detrimental to the steels ability to take a crisp, clean, burr free apex. That isn't so much determined by carbide volume, but hardness definitely plays a roll, as does how much austenite is retained during heat treat.
Based on composition, SPY27 should have a slightly lower carbide volume than s30v. Everything else will depend on how Spyderco heat treats the steel, and to what HRC. If they run it a little harder than s30v, it may give the steel similar grindability, but it should also allow it to take a finer edge, and deburr easier. On harder steels the burr tends to break off easier.
There are numerous other factors, and the factors I mentioned could be expanded upon a good deal, but the point is we won't really know until we get the steel in our hands. I'm hoping Spyderco will run it a point or two harder than their s30v, resulting in similar wear resistance, but making it a better sharpening steel with improved edge stability.
I preordered a Para 3 LW already, and am excited to get it in my hands.
