Are there plans to reopen the cable cars / aerial tramways in Tbilisi Georgia?

In Tbilisi Georgia there used to be a network of aerial tramways / cable cars which operated in various parts of the city:

• Georgian National Academy of Sciences on Shota Rustaveli Avenue
• Vake Park to Turtle Lake
• Photos of many of the locations are on this Facebook page: Cable Cars (Aerial Tramways) Tbilisi.
• More concrete details on the three or four others coming...

It seems that these would be very nice attractions for the city, providing stunning views and something quite unique. But it's incredibly hard to find much information about them, including their names and when they ceased to operate.

But most of all I want to know if the city is intending to refurbish and reopen them in the near future, especially considering all the other restoration and renovation taking place in the city in recent years.
