Nintendo France's Philippe Lavoue expects the Switch to clear the Wii U's lifetime sales in that region by the end of 2017.
Speaking to Gamekult, Lavoue says that Nintendo France anticipates end-of-year sales of 800,000 units, which includes 95,000 units sold on day one. He also predicts a near 1:1 attach rate for The Legend of Zelda: Breath of the Wild.
Lavoue also mentioned that at present, demand for the grey Joy-Con Switch unit is higher than the neon one, although he expects this to change in the future. He also speaks about 1-2-Switch not being a pack-in title; according to Lavoue, it simply wasn't possible to bundle the game with the console and hit an acceptable price point.
Sticking with the topic of software, Lavoue countered concern about Breath of the Wild and Mario Kart 8 both being available on the Wii U; he states that while Mario Kart Wii sold three million units in France, Mario Kart 8 only sold 350,000, meaning that there's plenty of scope for more sales on Switch. For Zelda, he points out that pre-orders for the Wii U version aren't even close to matching those for Switch.
Lavoue's bullish projections don't stop with the Switch; he also claims that the 3DS will sell 700,000 units this year, along with three million units of software. Given those figures, it's understandable that Nintendo France's stance lines up with the rest of Nintendo - the 3DS isn't going anywhere, at least not for the rest of 2017.
