Is switch rumored to have an sd card memory expansion slot?
Some people are speculating that vicarious visions is helping Bungie to bring Destiny 2 to switch. But it's just fan speculation.
That would be a huge win for Nintendo, but I haven't heard anything from Activision people about what their level of support for the Switch is going to be. Bringing a game like Destiny 2 is a big commitment with all the DLC and patches that come along with it
