Nobody knows exactly, but everyone hopes:)
Personally I'm looking forward for this presentation, I play with modo from time to time and for me it is the best software, but unfortunately I can't swith to it because of renderer, I just don't feel comfortable with it's native renderer in its recent form. I know that there is Vray and Octane for Modo, but both looks like pre-alpha versions of their native platforms. I guess they will show something interesting, if no - I think I'm not the only one waiting for Corona for Modo.
