I get what you're saying, but having tried out numerous "Smart" TV's - they're really not that smart. Banner ads, slow and clunky interface, poor selection of almost all terrible apps etc.
This is part of why I think the future of the Smart TV will be the Dumb Display. At least where Apple is concerned.
When the new Mac Pro comes out I won't be shocked if they revamp the Cinema Display line up with at least one larger size like say a 40 inch model. Give it the same lower glare treatment as the new iMacs, plus HDMI inputs, PPI and frame rates high enough to work with 3d blu-ray etc. if not in this run then the revamp. This time might hold off on 4k and 3D but might not if FCPX can work with them.
Then they revamp the little black box with more internal storage for rentals etc and revamp the store offerings using h.265 to make the 1080p higher quality for the same file size add more audio and subtitles etc. revamp iTunes Extras to be more 'disk' like. Push for filling in the gaps with missing seasons, lack of at least 720p etc. hopefully better release dates, prices and no more this 'so awesome you bought the season when it came out with no extras but you have to buy it again with this box set' nonsense like Breaking Bad has done.
Then in a year or two when downloads of 4k, passive 3d etc are viable they can just update the box. Way easier than forcing everyone to update a huge display, particularly if it already has the needed guts to handle such files.

This is Foxconn trying to "skate where the puck is going to be" rather than them having any specific knowledge or details at all about what Apple is doing.

It's more a combo of that and of trying to get into other things so they aren't making their money mostly off Apple. I think they see the possible writing on the wall that many of the big contracts might not come to them into total if at all. They see this big political push to make stuff in the US, at least what is going to be sold there, and can't promise they will have that money since there might not be a FoxConn US to handle it.
So they need to diversify and this was a way they could so that AND be prepared if Apple does do something in the TV or TV like display world.
