I'd love a giftset with brilliant box art from MMC, but that is not enough for me to risk the chance of not getting them. It's just a different case to as when MakeToys was releasing G2 Yellow Giant ahead of Green Giant - everyone knew a Green repaint had to be on its way, and the box art was just the bonus.
Also, demand for third-party not-Predakings may be further diluted from UT's release, so this may affect MMC's decision on releasing a second run.
