Can't you just buy a 2-pin to 3-pin adapter? I believe the PS3/Wii will be able to take input voltages ranging from 120-250V. When I went on holidays to US, I took all my handhelds, mobile phones with a 3-pin to 2-pin converter (cost approximately £1) and everything worked like a charm. UAE use similar voltages to the UK.
Just to make sure, read off of the power brick of your Wii/PS3 to check what kind of input voltages they can take, if it includes 220V in the region, then all you need is to be able to plug your system into the mains, which will require the above adapter I mentioned which you can probably find on ebay for $1 or 2.
