There will be no new Lumia's at this years MWC unfortunately
Microsofts BUILD conference in early April is going to announce WP8.1. Then I would think new models will be launched closely after and throughout 2014.
Nothing wrong in getting the 1520 though in my opinion, it's got great specs.
Yep, I'd say the start of April at the earliest for any announcements of new WP's, as they'd surely be running WP8.1 out of the box, so Microsoft will likely show off WP8.1 first, then devices come after (maybe almost immediately after though). Also, we'll have to see whether the first announcements will include any high end phones or whether they'll be low end phones, or a mix of both.April.. that long.. +2-4 months in my country.. or more
now i havee a dilemma if to buy sony xperia z2 or lumia 1520.....
