I have my preference set to Miles (as I'm currently participating in MegaMiles on stays this week), and don't see anything new, so I presume only MegaBonus (points) promos have been "announced" so far,
no new MegaMiles (miles) promo yet.
(I presume I could see my MegaBonus promo right now if I switched to points, but I don't want to switch to points until I'm done with my 3 stays this week and the posting of them. Since the next points promo doesn't start until June 1, I think I have plenty of time.
