OnePlus is rumored to launch a new device called the Nord 2T in India sometime soon. Now, it is slated to starting at ~US$400 in this market, and to be joined there by the Nord 2 CE for even less. They might be accompanied by a third variant, which does not have a name, but does have an alleged budget price-range, to date.
