What Ezer'Arch said ^^^^^^^^.
I expect that within 1-2 weeks after the 1.7.2 beta being released, there will be 1.7.2 and 1.7.10 versions of Galacticraft in parallel going forward.
The main difficulty is not compatibility with Minecraft 1.7.10 (we are already pretty much there with that) but compatibility with the 1.7.10 versions of other mods. Unfortunately one of the major mods which Galacticraft interacts with, that's IndustrialCraft2, changed how its API works between 1.7.2 and 1.7.10. Also 1.7.10 means Mekanism compatibility. I think guys who want to use Galacticraft in a 1.7.10 modpack will want to see it compatible with IC2 and Mekanism...
