Out of africa remains defensible but more and more people will come to the conclusion that the chinese hyporhesis of the multiregional origin is somewhat true so we will get a hybrid i guess
The problem is that "Out of Africa" is an uninformative name. The outflow from Africa was well underway 100k years ago or even 200k years ago, and there was no inherent break between that ongoing outflow and what happened 40k years ago when (inasmuch as we can reconstruct today) behaviorally modern rather than 'archaic' humans began to migrate out, which we now call "Out of Africa". So it's hard to even tell apart the "recent Out of Africa" and the "multiregional" hypotheses in a way that might help settle a debate.
