That's what it looks like. The Reveal catalogs this year are specifically divided into different sections, apparently based on availability. The first one is "Reveal," which includes new models and new "standard" variations on existing models (e.g. black blade. Then there's "Flash Batch" which is a "distinctive one-time-only event." Then they have the "Sprint Run" section, which is existing models in limited production steel/color variants. The fact that Reveal 4 (from early this year) had the K390 Ladybug and SPY27 Manix 2 LW and Para 3 LW in the Reveal section, followed by the Byrd Harrier Reveal, then the Flash Batch section, then the REX45 Sprint Runs, strongly suggests that K390 and SPY27 are not Sprint Runs and will be added to the regular full-availability product line. In Reveal 5, the SPY27 Native 5 LW and Mule Team are in the Reveal section followed by 4 more pages of Reveal Section. They mix it up by having a new header for "K390 Models" (Delica, Dragonfly, Endura, Manbug) but then it goes back to "Reveal" for two more pages (Pacific Salt 2 and new Byrd Harrier stainless-handle variants) before switching to the "Sprint Run" header. Oddly, the last page goes back to "Reveal" for the Swick neck knives, which might have been a late addition that got put in the back so as to not cut out their "artsy" photo spreads (the Pochi-as-pigs on p.2 and the dirtbike riding up a Swayback on p.6) while also not requiring too much re-working of the layout. My guess is that K390 will be used in the high-volume Seki City knives (i.e. the 5 that have been revealed) and SPY27 will be used in the US-made models. Those models being made regularly in K390 would be a significant development, since those models have never been made in non-Japanese steel in large numbers (the Ladybug 3 and Manbug have never been produced in any non-Japanese steel; the first variants of the Endura 4 and Dragonfly 2 without Japanese steel were this year's S30V dealer exclusives for MGE Wholesale; the Delica 4 has had limited-run dealer exclusives in S30V, M390, and Cru-Wear).
