Engadget is one of many reporting that Brother and NEC both seem to have retina display technology
in the works for release next year. Brother, at least, seems to have a fully functional prototype, while so far NEC is mostly talk. "Naturally, there are a few considerable limitations compared to more traditional displays, but the company's as yet unnamed goggles do promise to beam an 800 x 600 image directly into your retina that'll appear as a 10-centimeter wide image floating about one meter in front of them -- which is certainly no small feat, even if it may not be the most practical one. Slightly less specific, but also working on a retina display of its own is NEC, which apparently hopes to incorporate a microphone into their display and use it as a real-time translation device that would quite literally display subtitles as you talk to someone."
