If it's true, it's more likely that it's focused on the U.S. market primarily, so Ovi integration isn't a big factor. Ovi aside from, say, Maps, doesn't really contain much in there for a U.S. user.
It's a chicken and egg thing, but Ovi content was always more popular in Asia and Europe; you'll find soccer (football) and cricket score apps, London or Asian "tube" maps and a Tesco (a UK supermarket chain) app; also, the Nokia Music store, which caters to individual country musical tastes, but again, never launched in the States.
Nokia wouldn't be losing money by not offering Ovi....since Ovi services aren't making money for them in the U.S. anyway.
