The Pacific/Far East theatre has been neglected most, so I would say more maps for these areas are most needed. Some suggestions:
Luzon
Leyte
Northern Malaya and Southern Thailand (we already have Southern Malaya and Singapore)
Borneo
Southern Sumatra with West Java, plus a map of Bali with East Java (these in case 1C releases the CW-21B after all...... highly unlikely I admit)
