A lot of folks seem to forget the development and heritage of the 10mm, as originally envisioned by Cooper (200gr@1000fps).
It appears Speer is more or less returning to the roots of the 10mm, although they're boosting the velocity a little higher than originally desired by Cooper, closer to the developed load (200@1150) as it became the 10mm Auto, before Norma got involved and hot-rodded it a bit, and then also developed the lighter 170gr load.

I'd be a little surprised if many of the major American ammo makers would want to get involved in "magnum-izing" the 10mm, but handloaders and some smaller custom companies have been scratching that itch for some time. Of course, COR®BON has also been making 10mm for quite a while, and has some lighter bullet weight loads available.
I rather suspect that the new Speer load might appeal to the father of the 10mm, if he were around today.
If I were going to carry a 10mm today, and wanted a hot load similar to the older Norma loads, I'd be very interested in using the W-W 175gr STHP, which closely approximates the old Norma load of 170gr@1300, being listed at 175gr@1290. Otherwise, the Speer 200gr load looks like it would serve as a modern carry load for a CCW role, and probably shoot quite nicely from some of today's pistols.
