I'm sure that everyone here can speculate, and some have in the recent past about a 4K update of some kind to the V1 (which has been discontinued).
Generally speaking, though, B&O keeps major designs in their collections for a LONG time, here's a rough rundown of some of their modern televisions:
Beovision Avant (David Lewis design) (1994-2005)
Beovision 4 (2004-2013)
Beovision 5 (2003-2006)
Beovision 7 (2004-2013)
Beovision 8 (2008-2011)
Beovision 9 (2007-2010)
Beovision 10 (2010-2013)
Beovision 11 (2012-present)
While I don't want to speculate, I'd say that the Beovision 11 design (to me, a classic ) is iconic enough to last a while, and from a manufacturing perspective, the interior should be able to be upgraded relatively easily for better screens, or beosystem processor. sort of hoping that in the future, this "chassis" upgrade can be something owners can order and have done to their televisions in their homes.
Having said that, the Beovision 11 is already on the fourth chassis design in the past three years.
