There won't be an station at Mount Dennis when the UPX opens in 2015. However I believe the design for the new Mount Dennis GO station allows for a UPX platform in 2020-2022. Presumably by then the Weston UPX station will have closed because of a lack of ridership ... or some trains will stop at Mount Dennis instead of Weston.
Or, preferably, someone will have connected the GO line to the airport (as I have said before my preference would be an extended/revamped aiprort people mover at Malton) so that those on Eglinton can transfer to the more affordable GO system and those on the premium-priced UPe can get the express service they paid for.
Like you, I don't expect a long life for stops of the UPe at Weston.
