Just after we got this preview, I ran into the new Google Views with photo spheres. I managed to get most of my synth material, which a started shooting since early 2010, on Google Maps as 'Spheres'. Up to today, I have a total of more than 20,000 views. In 4 years having these as Photosynths on Bing Maps, I would be surprised to have gathered much more than 200 views.
Sadly enough this affirms low market share of Bing Maps and previous policy of having Photosynth as a separate Maps app as very low key.
I really hope we are going to see Photosynth featuring prominently on Bing Maps soon.
