update.1 "breaking" wrapped activities?

[Paul Fox]

in a description of how non-sugar apps need some help to run
properly under sugar, the current front page of OLPC News
contains the following quote:

    "...  there is some discussion that Update 1, a forthcoming
    upgrade to Sugar, will break all existing wrappers, and
    current Activities will need to be re-coded and re-wrapped."

the only "breakage" that i've heard mentioned on this list is
that of the activities moving -- i've seen nothing about the
environment changing so as to require wrapper changes (and i've
already commented to that effect at olpcnews).  can someone
confirm that i'm not wrong?
