If i buy note 5 dual sim. Will i have software updats in the future??

'm thinking to buy the note 5 dual sime sm n9208. From ebay cause i do not found the normal 64gb white version. Now my main question is if it will have updats in the future as the normal note 5 will get? Or ill have to always wait? In the other hand will it be able to install an 920 normal updats to it? Will it function as normal note 5or not? Thanks ls for the help!

P. S ill need hebrew support and sansung says the dual does not have hebrew support so will it be possible to just install a n920 version and use the note 5 as normal and not dual?
