Since swallowing up Nokia’s phone business, Microsoft hasn’t said much about its plans for the Lumia lineup, but a new report from @evleaks claims to reveal the company’s smartphone plans for the summer and beyond. According to one”well-placed source,” Microsoft will release two mid-range Windows Phone 8.1 devices in the near future in the U.S. The report also details something far more exciting.

The Lumia 635, a mid-range device announced earlier this year, will reportedly launch on T-Mobile, AT&T, and Sprint in either June or July. The Windows Phone 8.1 handset packs a 4.5-inch display, a Snapdragon 400 processor and LTE support. It should cost under $200 off-contract. Meanwhile, the still-rumored Lumia 530 should arrive on T-Mobile and the AT&T-owned Cricket in the third quarter of 2014.

The source goes on to hint that the next generation of mid-to-high-end Windows Phone devices will run a future update of the mobile OS referred to internally as Windows Phone Blue GDR1. A pair of mid-range devices called Superman and Tesla are expected to land on Verizon and AT&T, respectively. There’s also a flagship phone codenamed McLaren set to launch sometime this fall on all or most major U.S. carriers.

Looking even further ahead, the company’s plans for 2015 allegedly include two more AT&T handsets codenamed Makepeace and Dempsey, as well as a late-summer phablet referred to as Cityman and a flagship Talkman. It’s likely these plans will change between now and then, but it’s nice to see Nokia’s mobile team still hard at work on the next generation of smartphones after its recent change in management.

Nokia saw some solid success with its cheaper Lumia devices, but it’s still unclear whether it can do the same with a flagship Windows Phone. With direct support from Microsoft this time around it’s possible the Lumia lineup may finally be ready to break into the mainstream, though it’s still far to early to say for sure.
