Tons of blockbuster releases already on the format and a lot already announced for release by the end of the year, and all people can do is bit*h and complain....
I don't think it's reasonable or realistic to expect the floodgates to open so quickly for what is essentially a new format (the format war only ended about a year ago). These things take time, and HD adoption isn't exactly through the roof quite yet.
Not to mention the fact that if everything were released all at once, you'd just complain that you couldn't afford it all, and how you wished they would stagger releases to ease the hurt on your wallet.
I actually like getting excited when new things are announced, or an old favorite is released unexpectedly. You'll get much more enjoyment out of the format if you have things to look forward to and keep you interested, rather than just complain about how slowly things are coming out.
