Kong as well as a few other Knockouts, some lower leve X-divison guys as well as EY,Homicide, Davari (or whatever the fuck his name is) and possibly even No Limit and Daniels who I think would no doubt be picked up by the WWE.
Davari asked (and was given) his release weeks (maybe months) ago.
I think even though Hogan may not like Homicide and Daniels and maybe even Rhyno, they'll still be around unless they want to be released due to their friends who are high Hogan's list (Styles, 3D, Hernadez).
Kong asked for her release but never heard anything beyond that. To be honest I'm not sure WWE would want her or if I'd really want to see her in WWE. She stands out too much from the Divas and can actually wrestle which would make the divas all look bad. Hell they tried to do a power house diva (Pheonix) and eventually ended up making her into more of a diva than a wrestler.
My guess is that it's only a matter of time for Young, which really sucks since he's been around so long and now his spot is being taken by a Nasty Boy. To be honest it really wouldn't surprise me if they let go or split up Beer Money. It would be dumb I know, but I just have this hunch that it might happen.
As for the X-Division, they're actually talking about Destination X being an X-Division only PPV.
