Lesnar/Show looks like it'll be a hard-hitting, physical bout. Nothing too exciting, but I always enjoy watching Lesnar wrestle, so I'll check it out. After this, I guess they'll go their seperate ways. Lesnar, to the WWE World Heavyweight Championship, and Big Show... Who knows? Rumble match? I don't know who he could feud with.
Batista/Del Rio, I think it'll be a short-term feud. Similar to Lesnar/Show, it'll last for a month or two until Batista gets his shot at the title. It's different for Del Rio, too. I enjoyed his recent feud with Cena, because it was kinda refreshing. I feel the same about Batista/Del Rio. But, like you said, BITW, they should be elevating younger guys and boosting them. I guess some of those guys you listed are doing that already, though. Punk has been kinda boosting the Shield, and Bryan has been boosting the Wyatt Family. It'd be good to see those two in particular in main-event feuds again, although Bryan/Wyatt(s) is slowly becoming one of the biggest stories on the show, and Punk looks to be entering a feud with the Authority (slowly, but surely).
