This seems like a cool & intuitive technology, but I'd caution that (similar to the popularity of neck braces) it's far from definitive to provide additional protection. The general principle is MIPS (and others) allow the helmet to receive a rotational force without "grabbing" your head and twisting it as well, but unless you have a shaved head I find this is exactly what happens with the original MIPS, hair. So I'd say: (1) the science is still undecided in my opinion, (2) I wouldn't replace a new helmet just to get MIPS, (3)your next helmet is likely to have it because they all do.
