Warners, Universal (who also control Fox and Paramount) and Sony (who also control Disney) are fairly commercial in NZ, Road$how are still operating in 1983 believing that their content is somehow superior and they should be able to charge more for it (this could be one reason why they have lost control of so many major studios product over the last few years here in NZ), this is why I guess we are seeing more Warners product on their lineup.
TV on disc is one of the last few growth areas for studios when it comes to DVD, I would guess that they don't want to bastardise that market too soon.
The bulk of the foreign film market in NZ is controlled by Rialto (DVD distribution rights via Gamewizz Digital Entertainment) and Madman, both I would think would be keen to expand their market, but a lot of that product is so market specific, it could be a little scary for them to release it in this way, who knows (as our Gamewizz rep says, their movies almost always rent well, because who the hell bothers to download them, its not the market for foreign / arthouse films).
Even your most piss-poor video shop would have a wider selection than what is available from quckflix at this point, will be interesting to see how it grows.
Full unlimited streaming of HD content, maybe, anything less than that and its a bit of a gimmick
