No clue regarding the C-130 and Mi-24. I do hope they'll also release a 1/144 version of whatever Hercules they have planned.
Predicting Zvezda's 1/48 Hind schedule is a bit dicey, as they haven't released much in that scale, let alone a family of kits. If the do a Hind-A, it will probably be somewhere down the line, I think. My money would be on a Mi-24V/VP for starters (as in their 1/72 line), followed by a Mi-24P sometime later. They really took their time releasing the Mi-24P in 1/72 and released a Mi-35M and the Mi-24A in between. With some clever sprue breakdown, those two should also be doable in 1/48 without too much effort.
