Though, while I doubt Isayama would let the name of the origin of everything go to waste, I doubt little Titans coming from her arms are what he had in mind.
Though it might point to something bigger all things considering. Isayama does have this horrible (yet brilliant) tendency to make a lot more questions then answers, always spinning a mystery in every chapter he comes out with. Case in point, if you haven't yet, go read the bonus chapter in Attack on Titan manga (forgot the volume), and you'll see what I mean.
