the new (something)
Why does the speaker say "the new iPhone" instead of "a new iPhone"? It's because everyone expected a new iPhone to be introduced around this time. If you think your listeners know what you're talking about, you should use "the".
Use the phrase "the new ___" when talking about new products that have been eagerly expected. For example:
Have you heard the new Katy Perry album?
I can't wait for the new Harry Potter movie.
(a product) comes out
When a product starts to be sold, you say that it "came out". Use this to talk about electronics, books, movies, and so on.
I remember when the Playstation first came out, it was the most awesome video game system I had ever seen.
The Lost Season 6 DVD is coming out in a couple weeks.
After something "comes out", you can then say that it is out:
Is the new Will Ferrell movie out yet?
It's been out for a few weeks.
I've GOT to have it.
This is a phrase in casual English that you say when you really want something. When you express what you want in this way, you sound a little like an impatient teenager.
