The Lumia 502 (a.k.a. "Zeal) should sport a 4" super sensitive screen, 1Ghz dual-core processor, 512MB RAM, 8GB of storage, HSPA+, and a 5MP rear camera.
We are expecting a few new Windows Phone devices from Nokia next week at Mobile World Congress 2013. We'll know in the matter of days if the Lumia 720 and 520 are just the tip of the iceberg. More as things develop.
