So this is the important part:

[17:58] so the issue has now changed from being a wallet issue into some other issue ....
[17:59] <@Ukyo> kanoi: this is why there will be a public announcement

[18:02] Lost or seized?
[18:02] <@Ukyo> I am expecting all users to get their owed btc.
[18:02] seized then.
[18:02] <@Ukyo> sigh
[18:02] <@Ukyo> I am expecting all users to get their owed btc via me.
[18:02] <@Ukyo> and my control.

[18:04] <@Ukyo> VinceSamios: at this point shit "has" hit the fan
[18:04] <@Ukyo> just to what level is the issue

So the most likely explanation we will get is that Ukyo has lost control of the coins for some reason (seized by some authority? or by doing something stupid while manipulating the wallet?) And he cannot pay back until he regains control of the funds. When and how that would happen is still unclear.
