Not to say. Ultra may want some technologies that these companies are keeping for themselves or they may want entrance in a specific exclusive market... this might be their ticket.
Next logical step? Man I want what you are smoking. This isn't something that revolutionized computers in the way that they behave, it doesn't do anything other than cleaning up the clutter in your case and looks cool.
When Ultra first released their XConnect, everyone was bashing them saying it's the dumbest move due to voltage drops and resistance... large companies tried to attack the whole concept of detachable cables. Now you are saying it's the next logical step?
No; however, by and large, the *marketplace* is.
Note that only two PSU manufacturers are NOT on the list of defendants (specifically, Antec and PC Power and Cooling) as these two companies have no modular PSUs in their product lines. Further, it has been PCP&C that has consistently attacked the entire idea of modularity in PSUs (and they have not stopped since their acquisition by OCZ, which DOES carry modular PSUs under the OCZ brand), and it has been PCP&C that has been castigated for not having a modular PSU (even their two latest models, the Turbo-Cool 850 and Turbo-Cool 1200SR, continue their trend of non-modular single-rail PSUs).
