New Modern SPH for America maybe?

I mean the M109 is just a heap load of shit compared to the Pzh2000 and maybe the AS-90 too so I was wondering if we’ll ever see either the M109-52 or M1299 ERCA. Both were highly advanced and I believe both of them was proposed by BAE but please correct me if Im wrong.
