January is the official 'theme launch' for Universal's partners, but the idea is there should just be more classic Jurassic branded merch coming out between now and the end of 2018. Not sure what celebration events they may or may not have planned, but a lot of Jurassic stuff is happening next year due to Fallen Kingdom.
Mattel will celebrate the 25th anniversary starting around January with the 'Jurassic World: Legacy Collection', most of the items will be JP1 (with some of the other films for good measure.
Chronicle of course has a few items, like Raptors in the kitchen and more.
