I had the same question, but if you ask them to clarify, they'll let you know that they are in fact planning to release the phone this year.
Not that it matters what anyone from verizon says or tweets these days, but I'll bite.
Saying "scheduled to release" is the same as saying nothing at all. It's the same bs speak that politicians use. Like when someone says they have no current plans to run for president, then announce their candidacy two weeks later. Well, yeah, I guess what they originally said could have been true. Vanilla language that can't necessarily be contradicted. Saying "it will release this year" is much more of a commitment than merely "scheduled".
