"All six teams are interested in hosting at least one event in either 2015 or 2016 and we're working with each team to convert that interest into a concrete event plan."
The two confirmed host venues will announce their events in the coming weeks with the first announcement expected on November 5.
All racing in the World Series will take place in foiling versions of the one-design AC45 catamarans.
Powered by a highly efficient wing-sail, the foiling version of the AC45 catamaran will lift out of the water, riding on hydrofoils which reduces drag and increases speed.
"It will be a thrilling and spectacular sight to see these boats racing together in a fleet race format, and it will be challenging for the five sailors on board," Schiller said.
The final host venue announcement will be made in December with Bermuda and San Diego the remaining candidates to host the 2017 America's Cup.
"We're moving forward on the host venue agreement," Schiller said.
"Bermuda and San Diego have now submitted their final bids and in each case we have a potential partner who has presented a compelling event plan."
