Del Sol is rumored to sign every 6 months. And every time he's reported to sign, a picture of him with a WWE contract from a tryout camp in 2011 pops up and all of a sudden "ZOMG ITS TRUE SAMURAI DEL SOUL IS GOIN 2 DA WWE".
From what I can find, this story originated from SuperLuchas, which has a history of bullshit reports. Although for what it's worth, Resistance Pro congratulated him on Twitter, and in Gabe's latest WNN email update he said that "The rumors surrounding Samuray Del Sol will be addressed in the next uodate". Sounds to me like his appearance at the next PWG show could be his last. Either way, I really hope WWE keeps him in a mask, preferably his current one, or a modifed version because (a) I don't want to see him unmasked. Seeing Sami Zayn ruined his Generico era matches for me to an extent and I don't want that to happen with SDS, and, (b) That mask looks amazing. Could be a big seller with the kids. It's one I personally would love to get my hands on.
