There has been talk about the Four Seasons "being built" for the last 10 years.
If anyone can find some evidence for me, I'd appreciate it
It seems Four Seasons (not a third party developer) bought the property (end of Emek refaim) somewhere around 1997, and its been stuck in litigation and city planing since.
Due to the location it's hard to see it catering to the mehadrin crowd but I guess you never know.
The W sounds very prelimenary but I'd guess somewhere around binyeni Haeuma which the city is hoping to turn into a massive commercial center, the 25-min train to tlv will certainly help.
Personally I'm excited for the Kempsinki tel aviv, which is already in the works
