The Dubai developer building the world’s tallest skyscraper says the tower is on track to open this year, though the exact date remains uncertain.

Emaar Properties said that the shiny metal and glass Burj Dubai “is scheduled to open this year.” The statement said more details will be provided later.

The company previously said the more than 2,600-foot (800-meter) tower, whose façade still appears incomplete, would open in September.

Emaar’s profits and share price have been hurt by falling property prices in Dubai and elsewhere.
