It was reported in the press that he has 3 ongoing productions so I guess that would probably keep him busy till the end of the year. However, it was also reported that his company will not be renewing the contracts of the artists who have completed their contracts so it would seem that he could be in the midst of winding up his company.
Anyway, with Jack being portrayed as a serial skirt chaser in the media and his reputation hitting below rock bottom after his press conference, I would think that it would be near impossible for him to sign any new FEMALE artists in the short to medium term.
