Resolves "Nothing" if no switch-like hardware releases with codename "OSM" by year 2030.

If hardware with codename OSM does release prior to 2030 but we don't know what it stands for, the market close date may be extended until we find out what it actually stands for.

NOTE: It is quite likely we never get a direct answer to what it stands for, and I will set a high bar for required evidence. I need to be personally convinced with >99% confidence. Bet with caution!
