Availability of the new iPad Pro ?

We are fellow users, we won't know when it will be released there - when a date is set it will show on Apple's site : https://www.apple.com/sa/ipad-pro/

None of the Apple online stores ship overseas, so you won't be able to buy it from the US site

If you mean international shipping to Saudi Arabia then no - but you would be better off waiting until it's available there, if you buy it from another country and have problems with it you might have to ship it back to that country
