EX90 isn't EOS yet, but with the DX70/80 now capable of running TelePresence software beginning with CE8.2, they will most likely be the replacement whenever the EX90 does go EOS. I'd suspect that won't happen until CE software on the DX matures and the feature capabilities grow to be more inline with the EX90, as it is right now the feature set is close to that of the EX60. To read more about CE software on DX70/80, refer to the CE8 Release Notes.
For the Profile all-in-one endpoints, the replacement is the MX Series endpoints.
