No PROOF but when you buy as many gadgets as I do you notice things like the 1520 has been out for a few months and there is still no Otterbox ,only knock-offs. They (Otterbox) don't mention coming soon. I read here that someone called Otterbox and Otterbox said no plans for an Otterbox case. I don't know because I didn't talk to them, if they mean no plans EVER or for now. There is usually an Otterbox ready when a new iPhone comes out .. Same for the Galaxy phones. Some companies don't even make cases for the Nokias. Speck cases are not being made for the 1520. Why is that? Vaja for example makes beautiful QUALITY cases. For the price of the phone, I think it deserves Vaja Leather. If my business was making cases I wouldn't want to put into production a case where the phone will be old news next month. And the Nokia 1520 and/or the 1020 will be because there is a NEW Nokia on the way. Forgot the name, but it isn't a number. New phone each month would be GREAT for Nokia sales but as an accountant, I would say that is not the case with the accessory makers. I kept my iPhones until a new and different iphone appeared. EXAMPLE. I had the iPad one. I kept it for what seemed like forever and didn't replace it until apps were not being made for the OLD iPad and some apps wouldn't work at all with the iPad 1 .. I think I would have kept the Nokia 1020 for a long while .. I still have my iPad 2 and my iPhone 5 (not 5s because nothing changed except the fingerprint reader..) Besides I don't want Apple to have my finger print .. They shouldn't have it ....
