Supposed to be released in Feb.. Which means more like may..

OS .25XZ (http://www.redrc.net/2009/10/os-max-25xz-truggy-engine/)

My guess they did what all the other .25 manufacturers have done and simply shrunk the bore of the .28.. While it should help in fuel mileage I doubt the power is as useable as the .24 from Trinity or Orion..

I looked up the specs and compared to other OS engines. Looks like an original design as far as bore and stroke go.. After a quick look it is near square , but not quite. Might actually be as good as advertised.. but I'll be running Trinity, so it won't matter to me..
