got mine from Fb user on xbox malaysia group who helped a few of us buy a few units from Amazon UAE..stocks are plenty there, besides can even walk into physical stores some even offer discounts and can get it for less than retail price. Price after conversion is around Rm2.3k

Qishan is almost close to impossible to pre order now, let alone buy one ready stock from them.

I use GP rechargeable batteries + fash charging adapter, 2 hrs to fully charge 4 batteries.

Yes, you can use PS4 controller but you'll need to use an ipad/phone to connect the controller via remote play to the console. It works flawlessly.

If you want to have 2 players, just use the 1st xb controller on the main account and then your ps4 controller connected using bluetooth to iPad/phone and login using the 2nd account on your xbox via remote play.
