Next week’s new mb item includes, BBQ hot sauce, Independence day party hat, Pink party balloons and Pink mini fridge.
Mikan found them out when April surprise with a whole set! 
(I wonder what to do with mine)
As for the new weekly treasure hunt item, popcorn machine, Mikan digged 2 and sold both in the forum, she didn’t know what to do with them.
There is also a new island unlock in your world map, but you would have to get friends’ help by sending you the items to build a hot air balloon!

Mikan’s not that perk up about next week item, but there is one she will surely get:
The Limited deer seat!
There will only be 5000 released though, so be sure to get yours as soon as you can!
