Groundwork on MNC Park continues and according to a press release from July 1, construction is scheduled to officially begin during the second half of 2019 (which is of course anytime between right now and the end of the year). Also, according to the MNC Land Deputy Managing Director, MNC Park will be completed in either 2022 or early 2023. The theme park is being touted as twice the size as Universal Studios Singapore and in the same class as Disneyland.
