Similar to the answer Nikon executives gave to AP in an interview last week, Toshiaki Akagi (Department Manager in Nikon’s 1 Designing Department) told dpreview that a new large sensor mirrorless cameras is a possibility in the future:
“We know that there is a certain body of demand for larger sensors in mirrorless products. Although we already have the 1 inch sensor in the 1 System, we don’t want to deny the possibility of future large-sensor mirrorless cameras. So maybe if there is enough demand we may be able to provide another type of mirrorless camera with larger sensors. This is one of the solutions.”
