Is it true that so many app developers are dropping WP, because W10 is coming and the apps will be easier built from scratch in the new environment?
It's still predicated on money. Weather Flow was the perfect example. The app was really nice but the developer couldn't keep up with the financial demand required for the information due to lack of use. I do think you make a valid point, and ultimately that will have some impact, but the reality is most developers wasn't to see some return in their investment and with windows phone behind a separate entity from windows, they will won't to see how the universal store approach takes form. It's a smart business strategy and I can't personally blame them. Although, with snap chat, I'd have reservations for letting them developer for windows, as they seem to just be asinine for no reason.
