PS4 = has official support in Malaysia since December last year.
XBone = has no official support in Malaysia, and unlikely to have any support in Malaysia until half a decade after it launches in Singapore and the next generation of Xbox is on the horizon. For the records, it won't even launch in Singapore until later this year, probably nearing the end of the year.

Point still stands tho- they're launching in Singapore. When are they launching in Malaysia? For comparisons, the PS4 launched in Malaysia same day as Singapore.
