As far as I know, she is satisfied with what she has done up to this point and has no plans to risk changing things by starting a new project. I still wish she would write at least one more book, or even just give us some canon information about the new generation.
I would LOVE her to but I don't think she will. Because almost five years have past after she finished DH and she never took this long did she? so my hopes aren't that high.But honestly I wud love to know about the next generation...
She'll probably just put some stuff on Pottermore. But, really, I think the epilogue was supposed to show life for Harry and the kids- sure, they might have a few mishaps, but I think their life was supposed to be shown as normal. And, even if it was by the great JKR, who'd want to read about some normal kids being normal. OK, if it was by JKR, I'd read it, but I'd probably end up disappointed
