The handsets are said to be loaded, with the Lumia 1820 sporting a 5.2 inch, 2K display, Snapdragon 805, 3 GB of RAM, 32 GB of internal memory, and large 3400 mAh battery, as well as a camera with Nokia's post-shot focusing technology and Xenon flash. The design is said to be similar to the Lumia 928, which is certainly slimmer than the current flagships Lumia 1020. The other one, Lumia 1525, and will feature the same hardware specs and 2K screen resolution, but come with a 6 inch panel and 25 or 30 MP camera on the back, offering some sort of solar charging display panel. Windows Phone supports up to 1080p displays now, so 2K panels could mean another version is in store to be released soon, or perhaps just an update to the existing WP 8 edition, not to mention the Snapdragon 805 part, which won't be in devices before May. Microsoft, however, is said to be fronting extra Windows Phone manufactures with up to $2.6 billion to go towards the development of their own handsets, so eventually it has big plans for the mobile OS this year. Nokia seems to still be pivotal to them, though, if those leaked specs come even partially true. Source
