[Windows Central Question]

With cynogen mobiles having high end specs, should i go on to buy one Cynogen based phone for now and then update it with Windows 10 when it comes?

That's unlikely to work. There has been no announcement saying WM10 will run on any of their phones.

Since Windows devices already plenty fast despite it's spec why don't you get some current Lumia Flagship?

930 for starter or 1520?

The brief answer is: No.

[RumoredNow]

The collaboration between Cyanogen and Microsoft was to allow Cyanogen to offer Microsoft cloud services in place of Google's.

Outlook instead of Gmail
Bing search in place of Google Search
MSN maps replacing Google Maps
etc.

It is not a collaboration to allow porting of Windows Mobile over to Cyanogen OEM devices.
