From Sony's Patent:
Head-mounted display apparatus
US 20130069850 A1
The light source 251 includes a red-light-emitting element 251R that emits red light, a green-light-emitting element 251G that emits green light, and a blue-light-emitting element 251B that emits blue light. The light-emitting elements 251R, 251G, and 251B are semiconductor laser elements. Rays of light of the three primary colors emitted from the light source 251 are transmitted through a cross prism 255, thereby being combined into a single ray of light. The light enters and is collimated by the collimating optical system 252, which has a positive optical power on the whole, and is output therefrom as parallel light. The parallel light is reflected by a total-reflection mirror 256, and is scanningly moved by the scanner 253 in the horizontal and vertical directions. The scanner 253 is a MEMS and includes a micromirror rotatable in two-dimensional directions so that the parallel light received thereat is scanningly moved in two-dimensional directions. The parallel light scanningly moved in such a manner is imaged two dimensionally, whereby virtual pixels are generated. Light from the virtual pixels is transmitted through the relay optical system 254, which is a related-art relay optical system, thereby becoming parallel light, and the parallel light enters the optical device 120.
If to be compatible with an in-dash CarPlay touch display, it makes sense that Pioneer's AR HUD would be able to display head's up content uniform with Apple OS. Today's news reports must not know this.
My take on AT's comment is that he was trying to defuse the assumption that the North American Christmas holiday still amounts to the mainspring for new product launches. That it's overall significance is trending down on the world economic scene. Or, that a product sometime this year may launch in an Asian country.
Let alone the general public, after years of exposure, the tech media still don't *get* the workings of MEMS laser-based projection and sensing--to appear mainstream in a matter of months
Yet another cutting edge Apple patent revealed in this video of the new iOS in the Car; *Touch and Hover*.
Watch from :35 to :38. The driver touches temperature control and guides the slider bar upward, without touching the screen surface..

The Patent referred to describes a projected instrument cluster, can be found here:
A novel form of touch interactivity is detailed--including differentiated driver/passenger views of the rear-projection display. How cool is that?
The patent mentions MEMS laser projection as an option, with words like:
"Use of lasers helps in high sunlight environments in the car"
A few frames at :40 show a digital instrument cluster which looks to be the same type of display with the same typeface..
At about 6 seconds, notice the finger tip coming toward the screen--as seen from an empty space behind the screen's surface. Suggestive of *projected* content, a new form of touch interactive, and so happens to line up with Apple's recent patent for this.
An aspect of PicoP technology long anticipated but not yet seen. Laser-based MEMS offers high-brightness, an ultra high contrast ratio, and superior visual resolution--night or day. Besides high brightness, this type of display offers a significant reduction in physical size and weight--and reduced waste. A compact hardware component only needs replacing. In addition, display content from a single engine can be routed and configured in unique ways. We will see.

Lasers are preferred for daylight readability.
Forward facing aperatures on bottom. One looks familiar.
A bit of further speculation and looking back in time:
Referring to the photo of the phone's array of projector/sensors, the rectangular aperature on the left does not appear to be a lens--rather appears to contain a surface with an elongated hexagonal feature resembling an exposed MEMS scanner.. The feature's dimensions are alsosuggestive--and if true, the dimension of the leftmost opening would have determined the dimension of the other shallower device openings as part of an expandable or interchangeable accessory type design, and is what in part determined the overall size of the workhorse phone.
This is speculation, of course. I would dismiss this possibility if Panasonic had not demonstrated focus free laser pico projectors at CES 2012. Engadget had the only detailed photos then.
