For what we all know Windows Phone Tango would be the next update from microsoft Post the Major Mango update we had a couple of months ago.Apparently a Tango Build 8713 was spotted by the benchmarking app for Windows Phone the WP Bench app,as  reported earlier by WPSauce.

Earlier Tango was supposed to be the 7.10.8200 build but now it seems that there are some changes made in the Tango update front also we can expect two different builds for Tango according to some hardware changes made earlier last month with the updated chassis.

Windows Phone Tango is supposed to be the intermediate update that is Post Mango and Pre Apollo update.Apollo which would be the next major update for Windows Phone which is rumored to be released some time next year.So Tango would be released some time in between along the roadmap for the Apollo release.
