I've been wondering if Sam Coupé and/or Sharp MZ series are being considered for implementation in the PLD. Those could be more important than the MSX in certain parts of the world.

I think msx was sold more than sharp mz or sam coupee' but... sam coupee' is a great little home pc because its architecture is similar to speccy and was compatible with it. In its mode it has a bigger resolution.

SAM is being regarded as one of more developed ZX SPECTRUM models. Also technology from Spectrum Loki was used while designing of SAM.
