I wonder what the lumen output will be?
All too rich for my blood but it sounds like a real winner!
I have to say it's pretty ironic that I said this earlier in this thread:

Currently, all home cinema/theater laser projectors (except for the Barco Thor) are singular blue laser through yellow phosphor, via which the red and the green components are synthesized.
I have seen over the course of the past 24 months some prototypes and new digital cinema projectors that are dual red and blue laser, and create only the green via a phosphor panel. This has numerous advantages as compared with singular blue laser, including the potential to deliver much of the chroma performance of 3P RGB laser but at a fraction of the price...
So what I would love to see is some home theater/cinema projectors making use of dual laser in this regard.
The only projectors capable of 100% of BT.2020 ar 6P RGB laser projectors wherein these actually use TWO lasers for each of the Red, Green, and Blue, with differing wavelengths for each colour so as to achieve a wider wavelength coverage for all of red, green, and, blue.
So with respect to dual red and blue laser, plus green phosphor, we should expect a significant proportion of the performance of 3P RGB laser, but at a fraction of the price.
A big issue with respect to the singular blue laser through yellow phosphor projectors is achieving good coverage of DCI-P3 whilst at the same time having both the primaries and secondaries accurately track BT.2020
This is why DCI-P3 coverage in itself is incomplete information. It's possible to have one projector have a higher percentage coverage of DCI-P3 than another projector, but the other projector to produce superior chroma performance if the former doesn't track the BT.2020 primaries and secondaries as well.
With singular blue laser through yellow phosphor projectors it is either the case that you need to use aggressive BT.2020 colour filters which hammer luminance, or less aggressive filters that reduce luminance less but which fail to achieve 100% of DCI-P3 let alone BT.2020, or opt to have no filter, as per with respect to the SONY 885/760 for example, wherein again these fail to achieve 100% of DCI-P3, and typically won't track BT.2020 as well as when filters are used.
Also, when no filters are used it is often the case that the red component is maxed out to the extent that it is on the threshold of clipping, as is the case with respect to the SONY 885/760, which makes accurately calibrating the projector to D65 white point without losing a lot of light output a nightmare.
With dual red and blue laser plus green phosphor, the benefits should be all of:
(1) Significantly increased and accurate coverage of both DCI-P3 and BT.2020;
(2) Either no need for BT.2020 colour filter, or significantly less aggressive filter(s) which reduce luminance to a far lesser degree;
(3) Able to accurately calibrate to D65 without losing as much light ouput/luminance;
(4) Superior chroma performance in more ways than one;
(5) Increased light ouput / luminance, although with the addition is red laser this probably won't be a large increase
