There's a variety of even more efficient MIMD processors. Eg, rex neo, adapteva epiphany, etc. The reason I don't see ARM being very competitive is that ARM processors have no discernible advantage compared to a clean slate ISA design. What exactly does ARM offer that the Rex Neo doesn't? By contrast, the Neo is far more efficient, doesn't waste energy on OoO, has no caches, making it far more efficient (especially in terms of data movement, which is a big deal) and has the advantage of having a simpler decoder.
