Where is Edwin De Los Santos?

What happened to Edwin De Los Santos? He shell shocked Jose Valenzeula and Jose himself was fresh off a first round shellacking of Francisco Vargas. Valenzuela was touted as a prospect to watch out for and Santos killed the hype and should have taken the prospect hype for himself but there's been radio silence from their camp. Santos should be fighting in Jan. or Feb. but it doesn't look like anything's lined up. It's like they missed their window of opportunity to cash in on that KO of Valenzuela. https://www.youtube.com/watch?v=-2fkTKa1jDo
