Microsoft is hitting the entry-level smartphone market heavy and often. At Mobile World Congress 2015, the new Lumia 640 and 640 XL as well as Acer's Liquid 220 budget smartphone made their debut, showing Microsoft's continued support of budget-friendly devices. Yet we're still left without any mention of the Lumia flagship devices Microsoft hinted at earlier this year, which eventually led to speculation on a high-end Lumia smartphone that could be poised for a pre-Windows 10 launch.
Keep dreaming, because in an interview with The Verge, Microsoft's director of phone marketing, Neil Broadley, cleared the air on the question of a flagship Lumia possibly launching ahead of the big Windows 10 launch:
"We believe the best time to bring those flagship devices to market is when we have our very latest flagship software experience available. We’re focusing our flagship development for slightly later when Windows 10 is available."
The direct comment by Broadley definitely puts to bed the idea that a Lumia flagship would be ready pre-Windows 10 launch. This doesn't mean other manufacturers wouldn't look to push flagship devices onto store shelves with the option to upgrade to the upcoming OS, but that notion is becoming more of a pipe dream. Windows 10 is expected to launch in the late summer/early fall 2015 period.
