My five cents:
MM-6 is a multimedia-enabled monitor (based on LP-6 I assume), given the outstanding track record of LP-6, it'll probably be pretty competitive at the price point and market segment.
IN-UNF looks to be beefed up 2.1-esque (XO is rated at 280Hz, so not exactly a 2.0+subwoofer, but the bass driver does have a separate enclosure, so it is similar in principle) system, I am a bit worried about localization given the higher crossover frequency... and its price, which isn't too far from the IN-5, I understand that sometimes one could use the extra space savings, but I think the UNF is shaping up to be a niche product. It's priced quite a bit taller than the typical "speakers tucked under the monitor", and there are better options around the same price if one just wants a pair of studio monitors. That's all just speculation though, and I may well be wrong.
