Trailers inside extras - a rare breed?

[derek_1999]

With the current extras debacle on Star Trek into Darkness (various extras spread around vendor specific versions), I was also wondering if anyone else has noticed that the movie trailer/teaser/TV spots are now pretty regularly omitted from most Blu-Ray's extras... or maybe it's just the movies I'm buying?

For example, I'd expected the teaser and full trailer for Oblivion... but nope, not in the extras.

I first noticed when I got the Immortals disc - I really liked the various teasers/trailers (better than the movie, it turns out!) but not much was on the BR.

Maybe its due to the web and trailers being so prolific there... but I'd quite like a copy on my BR of the movie

Now, I presume that a BR won't come with the movie's own teaser/trailer - and am pleasantly surprised when it does!

Interested to hear others chime in on this...
