Microsoft will reveal nine new Windows Phone handsets during its Windows Phone “Mango” press conference on Tuesday morning, according to WMPoweruser. Samsung is expected to have the lion’s share of devices with four new models, HTC and Acer are both expected to launch two, and Dell will supposedly reveal one. Reportedly, Samsung’s Windows Phones will bear some resemblance to its Galaxy S II device, and we’re hoping the phones are equipped with Samsung’s stunning Super AMOLED Plus displays, too. The new devices will hit the market in time for the holiday season according to the report, but no launch details are expected during the announcements. We’ll be reporting live from the press conference tomorrow morning at 10:00 a.m., so stay tuned for more.
