This is not another type of rumor in the market, like the deceptive one making rounds heralding the delivery of Windows Phone 7.8 update on 28 November, 2012. The following is pure guess-work – presumptions from past happenings!

From the past:

  1. 26 June, 2012 – Windows Phone (7.5) Tango update for Nokia Lumia 800 was spotted on Navifirm
  2. 02 July, 2012 – Tango was officially rolled-out to Samsung Omnia W(also to Dell Venue Pro)!

Current news:

Navifirm-Lumia-510-lumia-800 Are we just a few days away from the official Windows Phone 7.8 roll-out?

  1. 13 December, 2012 – Windows Phone 7.8 for Nokia Lumia 510 and Nokia Lumia 800 spotted on Navifirm
  2. 19 December, 2012 – well, we all have to wait for the roll-out to happen for devices like the Samsung Omnia W, HTC Radar, etc – let’s just hope this happens before Christmas!

Also, do note that, suddenly, AT&T updated Samsung Focus 2 to Windows Phone 7.5 (yes, Tango build 8773), just a couple of weeks ago. May be it’s just a ground work for the upcoming Windows Phone 7.8 update.
