  In May there's a new Guard Codex. The Conqueror is STILL not in that Codex(but the Vanquisher, Exterminator, Executioner[with 3 blast shots!], and the new Punisher and Eradicators are, and some people are wary of 
FW rules) and tanks are rumoured to gain the ability to fire their sponsons on the move(not with Ordnance firing, of course, but if you lose the Russ Cannon, sponsons still keep the tanks firing and useful). Also, we don't know if the rumoured 3 Russ for 1 
HS slot only applies to MBTs or any variant. 
 I'd wait until May before deciding, actually(especially since 
FW will probably errata 
IA1 in May and may make the Conqueror even MORE redundant thanks to the Eradicator[which is basically the Conqueror]).
