New regulatory filings may hint at new iPhone models coming earlier than this September. According to a MacRumors report, the French website Consomac first reported new Russian-language regulatory filings in the Eurasian Economic Commission (EEC) database that indicate 11 new iPhone models all running iOS 11.

The model numbers in the filing are all different from existing iPhone model numbers, which means all 11 models would be totally new iPhones. The EEC has a decent track record in revealing new Apple device model numbers: in February, the EEC detailed two new iPad model numbers, and those ended up being the identifiers of the two new 9.7-inch iPads that debuted in March. The EEC also had the model numbers of the new MacBook models revealed at WWDC 2017 one month before they were announced.
