It’s clear that despite the initial sticker shock reaction to the higher-than-expected $599 price tag, the demand for the consumer Oculus Rift virtual reality headset has been overwhelming. The first batch of units sold out within minutes, which pushed the estimated shipping date back for later purchases into April, then May, and now further until June 2016.

According to an interview with Polygon, Oculus founder Palmer Luckey expressed that the headset was selling faster than the company had anticipated, which explains one of the reasons why some customers were temporarily experiencing issues placing their orders on the Oculus website due to its high traffic volume.

“We sold through a lot faster than we expected,” said Luckey. “I can’t talk about numbers, but we sold through in 10 minutes what I thought we were going to sell through in a few hours, which is one of the reasons the site was beginning to buckle.”

Recently, Luckey also confirmed via Twitter that some pre-orders will be moving forward as the company makes sure “fraudulent orders are weeded out.” So, any customers expecting their Oculus Rift in either April or May could possibly see their delivery date bought forward even sooner.

The Oculus Rift will begin shipping its first wave of pre-orders on March 28th, and come bundled with an Xbox One controller, a sensor, cables, Oculus Remote, including two free games Lucky’s Tale and EVE: Valkyrie.
