It is unclear though if OnePlus will launch the regular OnePlus 7 at the May 14 event as well, and a OnePlus representative declined to comment on the matter. It would make sense that both phones are unveiled at the same time though, and there have been rumors that speculate that both will debut at this date. In any case, CNET will be covering the launch of the phone, so check back for more information when the event kicks off.
