High Fidelity Review is probably the best, but sa-cd.net is also a good one for upcoming info.
Yeah, day and date is a problem, but then remember back in the early days of dvd their were hardly ever any day and date releases either. It took almost two years before studios really started putting out most titles on dvd day and date with vhs.
I think a lot of the problem in this case with getting titles out is convincing the artist/management that it's worth mixing an album for surround. Right now albums that get surround releases tend to do so more because the artists and their managers or engineers want it and are willing to spend the time and money on it, rather than because the record company wants it. If more top selling artists demanded a day and date surround release (be it dvd-a or sacd), you'd see more of them. But it seems to me most artists, at least the big selling ones that might really help push the format to the mainstream, don't care about surround or hi-res.
My suspicion, sadly, is that sacd/dvd-a is always going to be a niche market like laserdiscs (which rarely released day and date with vhs). If the mainstream public is willing to settle for crappy sounding compressed downloaded mp3s over cds, which seems to be the common trend, then convincing them they need an even higher resolution format like sacd is going to be a tough sell. Cds caught on with the mainstream not because they were superior sounding to vinyl (yes, I know that's open to debate, but that's a different discussion), but rather because they were more convinent by being smaller and less prone to wear. Sacd's don't offer any benefit over cds except the sound quality, which is admittingly a major benefit to those us here, but less important to the majority of joe sixpacks and teeniebopers who make up most of the marketplace. Now, before you flame me for saying all this, let me say that I take no joy in any of this. I love sacd and dvd-a, and I'll be buying them as long as they put them out. But realistically, I just don't see them ever catching on with the mainstream the way cds and dvds have.
