Looks like Metro Manila residents will have more fun traveling around the Financial and Cultural Districts soon. The PPP Center has approved the establishment of the Manila-Makati-Pasay-Paranaque (MMPP) Mass Transit System, that will connect Makati, CCP Complex and Manila Bay.
Initial plan plots its start from C5 in Taguig, going through the Makati CBD (via Buendia), crosses Taft Avenue to get to CCP then Mall of Asia, then finally EDSA-Ayala. From there, you can ride the Fort Bus to go to The Fort and Serendra/High Street.
See below the statement from the PPP Center website.
Metro Manila Directions tried plotting where these stops might possibly be located in Google Maps (of course, not accurate yet) :
