I know, Bronk, I did'nt see that post by pyro...But, IF they were to give us a 25H, with the 75, then we could have some hope of seeing the Tse-tse fly, or 410 with the 50mm gun. I mean, the cat would be outta the bag, so to speak.
How the 25H would impact the arena's is only a guess, It would depend on ammo options for the 75.(AP wielding Mitchell's in TT, for example, or knocking out CV group ships with HE.)
