The two things I'd like to see are
1.) Medium format mirrorless with interchangeable lenses. I think this is more likely to be from Sony, Fuji or Nikon (I only mention Nikon because they seem to have had a prototype floating around some years ago - nothing about their recent behavior suggests they'll release something innovative like this) than a classic MF maker.
2.) Some innovation in printers. The best selling fine art printer today is the 5 year old Epson 3880, and the most recent printers released are the iPF x300 series from 2010 (the x400 series are a very minor revision!). I'd love to see a 24 inch printer in a more compact form factor (don't laugh, the old DesignJet 130 was no larger than a 3880, although a different shape) designed for individual photographers rather than print shops. I'd also like to see a 3880 type 17 inch printer with a more modern inkset (yes, there's the 4900, but it is as bulky as a 7900 - some dimensions are actually larger). Even the best current inksets can't quite keep up with the full gamut of the best sensors we have today (various MF sensors and the D800(e)/D810/A7r sensor), so there is some room for a still further improved inkset beyond the current Epson/Canon generation. It would be nice to have more choice in roll/sheet hybrid printers, beyond only the 4900 - many photographers (myself included) do greeting cards or small prints as well as larger art prints.
