Lumia 730 or waiting for new phones?

[Windows Central Question]

Hi,

I want to buy a new phone. I currently have a Nokia 701 (belle) and it's a great phone. Unbreakable, perfect maps, just the software is not supported anymore and therefore many things are not working as 2 years ago. (only maps, whatsapp and facebook)

I am looking for a dual sim phone + sd slot and preferebly "here" maps <300?
The 730 sounds pretty good.
Is it possible to save the maps on a sd card?
I am just thinking that the 730 is one year old already. Shall I get it, or wait for a successor? Is a successor even coming?
I would like try a windows phone (they took over nokia, and i just love my noke) but not sure if something will come soon. I can keep my phone a bit longer if I really have to...
Or are there any Android options that are better and i should consider?
Is it possible to safe the maps on a sd card @730?

thanks a lot for the help

What's ur budget. Lumia 730 though old but not obsolete.,that's a smart budget phone with awesome specs. But well if ur not worried abt budget then wait for new phones that would get released in a couple of months with windows 10

I have an 830, works just fine to be honest. It is a lot like the 730. Yes you can put the maps on the SD card. If you can wait, I would but you probably won't regret getting the 730
