Regarding talent, last night we saw DDK (Daniel Kapadia) co-cast the Eleague Online Qualifiers with Jorosar. It was a very odd dynamic as you could tell the bulk of the broadcast was carried by Jorosar, with DDK displaying a clear lack of knowledge regarding abilities and meta. Any investigation into DDK will tell you that he is someone concerned heavily with self-improvement and I believe that given a nod from FACEIT (to whom he is contracted) he could become a vital part of the scene.
Furthermore, Thorin, who is contracted to ELEAGUE for CSGO, has been showing initial interest in OW through retweeting articles and montages. To quote him from his AMA,
"The problem with Overwatch is that right now the majority of the appeal comes simply from its status as a fun casual game, which is very different to being an esports game. In esports games I want either fantastic gameplay and tactical depth or for there to be a huge scene with lots of players and events. Right now Overwatch has yet to display that it has or will have either, so I am waiting to see what happens."
He also confirms that he's had offers for deskwork based on the character he can bring to the desk. It wouldn't be a surprise to see either two at the LAN finals which would itself be a progression to solving the talent gap televised OW faces.
