Hopefully the next season is less predictable than the last. Honestly, the only thing that surprised me last season was when they (SPOILER)had to move the island. Everything else I saw coming a few episodes out, and I called the big reveal at the end of the last episode way back when I watched the season 3 finale.
I didn't find it that predictable myself. Nothing too shocking but still I didn't have it all figured.
And yes it'll be back late January/early February.
