According the news and sources:
Cathay Pacific will be moving to Terminal 4 next year 2017. There will be no Skytrain connected to existing terminals T1 T2 and T3.
Also, arriving and departing passengers will be segregated in T4 airside unlike the existing T1 T2 T3 airside, where departing and arriving passengers are mixed.
Does this mean, CX departing passengers in T4 airside will no longer have access to T1 T2 T3 airside? (Where all the sunflower / cactus / butterfly gardens + Entertainment deck + Social Tree are located)
Will be forced to take SQ in the future if this happens, which the fare / holiday package will be slightly more expensive and more troublesome to book.
I want to experience T1 T2 T3 facilities (via 24-hr Early Check-In) before my flight to vacation.
