For the new trends, its undefined, as it obviously hasn't happened yet (and any suggestion is simply speculation), but it is difficult to argue that there won't be one; whatever it is, the idea goes, it'll likely be missed.
As for who is in a better position to serve these new trends, it of course depends on what trends actually appear. It might be one of the giants of industry, if the trend matches, or nears a bet they're already making. It could also be some current minor player, who catches or forges an unexpected one, like Apple had.
Obviously the big players are in the best position to execute on a new trend (and hedge their bets), but as the idea goes, a giant might be large but he is slow, and therein lies his weakness. Encumbered by what they have now, its difficult to see new horizons (which is why things like google x and bell labs exist, divorcing themselves from the primary business in hopes of gaining insight)
Of course, all of this is a non-answer, I'm just describing the idealogy leading to all these death statements, but it's all you'll get out of me
