The OnePlus 6 is the successor to the OnePlus 5T, which matched or surpassed the Galaxy S8's hardware specs for around $200 less, but lacked waterproofing and wireless charging.
OnePlus is likely to undercut the Galaxy S9's $719 price tag, but some builds of the OnePlus 6 will probably creep up much closer to Samsung's price due to the cost of storage. The top 5T variant had 128GB of storage. However, the OnePlus 6 is still likely to come in well under the iPhone X.
OnePlus confirmed last week that it will be following the iPhone X's notch design albeit in a narrower cut-out and with fewer sensors. Fans were not pleased with the notch decision, which may have prompted OnePlus co-founder Carl Pei to delete his tweet: "Learn to love the notch".
