No, they didn't. Bloomberg published an article following the financial report which included a quote from an analyst who didn't expect new hardware this FY. VGC published their own article, citing Bloomberg as the source, claiming Nintendo said they weren't going to release new hardware this FY. They later removed this from their article, but as other outlets had repeated VGC's claim by that point it just kept being repeated. Nintendo published a transcript of the Q&A a day later in Japanese and a couple of days after that with an English translation, and neither had any reference whether they would release new hardware this FY.
Edit: The Bloomberg article also stated that Nintendo's 15 million hardware forecast didn't include new hardware, but that's a very different thing than saying there's no new hardware. Nintendo historically haven't forecast sales numbers for new generations of hardware even when they've been announced.
