Going by the leaks so far, looks like Henri IV is going to be essentially a Moskva that trades HP, 1knt of speed, maneuverability, radar, AA, and RoF for better alpha, gun caliber(240mm, about 9.45in), engine boost(!), and torpeedus (a set of 3 to each side).
Shells have a lower initial velocity (845m/s: for reference Fiji, Belfast, and Edinburgh all have 841m/s initial velocity), but due to the increased caliber (and thusly weight), I believe that Henri IV's shells will retain their velocity better than, say, Des Moines or any of the RN CLs. The arcs should be somewhere in between VMF railguns and USN rainbows, probably closer to VMF than USN.
So far, definitely looking forward to this! ^_^
