Usually i take a look at Celcom/Digi/Maxis/Umobile pre-order, you get a good gauge.

This year, only can see Maxis.

iPhone 7, all available, except for Jet black 128gb and 256GB is out.
iPhone 7 plus, all available except for Jet black and black 128GB, limited on 256GB.

Pretty much matching the trends of other countries that launched earlier.

Those physical stores (machines, macstudio etc), should have similar percentage of stocks, so have to be early.

Demand is much lower, but I think it's because the design didn't change and everyone holding back for next year which is the 10th anniversary for iPhone and Apple expected to do a drastic change.
