Ray Frankz: The "new" thing is that the Special talk that is given near the time of the celebration will be now given by a branch representative or governing body member and then everybody will watch through the screen.
Pardon? The OP is about this weekend Saturday 7 and Sunday 8 October 2017.
The Special Talk - presented as a pre-recorded video - is being held on Sunday 25 March 2018 for most congregations (ie week starting Monday 19 March) - unless you have a circuit assembly for circuit overseer's visit, in which case you'll have the Special talk a week earlier.
I understand most congregations will have a local Branch Committee member give a 'model public talk' (pay attention elders and ministerial servants!!). I do not believe any of the Governing Body will be recording a Special Talk - what is your reference for saying they will be, please?
