HTC is likely to unveil the HTC A9 “Aero” on September 29 alongside another high-end handset

Last week, HTC teased an upcoming “handsome” smartphone, leading many to believe that the handset in question will be the often-rumored HTC One A9 “Aero”. Unfortunately for those of you with an eye for high-end smartphones, it turned out that HTC was referring to a mid-range model, the HTC Desire 728. In less than 24 hours since unveiling the Desire 728, however, HTC started sending invites to an event where not one, but two high-end smartphones might see the light of day.
