It all depends on E3. The Mario Kart 8 should maintain itself through this week, since I doubt all the people(casuals, and those who didn't had the money at the moment or were payed in those days) got it on Friday or Saturday, so it should carry to this week. The Luigi Death Stare meme and videos, should also help spread the news that the game exists, and it should help maintain numbers, its appearance in Fox 5 News should also help a bit.
If Nintendo can bring a great E3, with some awesome news, and reveal stuff, that people have been asking for ages, it should be enough to maintain another week of sales, and maaaaaybe, along the Mario Kart 8 effect, give atleast a 55-60k weekly baseline to the console.
