Yaris is the prime competitor for honda city and an ideal replacement for Xli/Gli or 1300cc Corolla. Bezza is smaller car.
Pakistan being the biggest market for Corolla in south east asia, Toyota wouldn't want to make a blunder by replacing Corolla base models with bezza. So its definitely the new yaris sedan avalible everywhere in Asia.
Bezza if launched would definitely be launched with a daihatsu badge, with bezza being the sedan version of Mira hatchback.
