This is not the first time that Watchtower has had a convention featuring Jesus. Have you all forgotten about the "Follow The Christ" district convention several years ago?
This convention is just part of their periodic, token focus on Jesus that they do just so they can say that they're christian. Like another poster alluded to, this convention will just use Jesus to preach Watchtower propaganda. You can bet that Jesus would often be objectified as "the ransom sacrifice" and depersonalized as "spirit creature". Watchtower has no true love for Jesus and this shows in their writing.
To Watchtower, Jesus is just an inconvenient obligation that they have to begrudgingly attend to periodically so they can claim to be christian and justify their claim of having Jehovah's favor. There is no true heartfelt love and honor for Jesus among JWs, as is evidenced by the conspicuous absence of his name on their tongues outside of the formal doctrinal teaching and learning sessions where he is mentioned from the stage.
Just look at all the JW jargon that JWs typically use in conversation: "Jehovah's Organization", "wait on Jehovah", "servants of Jehovah", "serving Jehovah", "Jehovah's people", "Jehovah's direction", "Jehovah's spirit", "Jehovah's blessing" ... you get the idea -- it's all about Jehovah. Can you think of any often used JW jargon that has "Jesus" in it? That says volumes! Even when JWs do try to focus on Jesus they go out of their way to give him measured focus as if trying to be careful not to give him too much focus for fear of being guilty of worshiping him. Contrast JWs lack of use of the name Jesus and lack of verbal praise of Jesus with the NT writers' focus on Jesus and their unabashed praising of him in writing.
