Sig has suggested that they will be adding to their modular lineup with the sig p320, which is the same concept as the 250 but is a striker fired design. I heard somewhere back around shotshow that it would be compatible with the p250 platform, but i don't know to what extent.
Most of the problems with the p250 were from the first generation line that featured a weaker plastic, plastic guide rod, and proprietary sig rail. The gun felt chintzy and was likely to have the polymer frame parts wear down causing the modular rail caddy piece and other pieces to fit loosely, leading to a host of other problems. The second generation of p250's remedied these problems and made a solid pistol. I imagine if you change the frame all the time in the 2nd gen, they would eventually wear out as well.
Sig had a similar problem with their SigPro 2020 (short lived piece of trash) which was replaced by the SP2022 (great budget Sig).
