Jloveys, the licensing with EMI, who now own the Blue Note catalog, determines the number of copies Music Matters and Analogue Productions are allowed to press. This is a very expensive undertaking, and from Joe Harley's comments posted on the Hoffman Music Forum it is quite apparent that EMI is monitoring the quantity pressed quite strictly. Could they have contracted to press a larger number? Possibly. But they are the ones who had to pay the entire press run licensing fee up front and find the capital to do that, not you nor I.
As to the sonics of these 45 rpm stereo reissues, The folks behind this effort are quite clear on their objectives: they are trying to put onto vinyl the best sounding pressings of these master tapes possible, not trying to match what folks may be used to hearing on the originals, but to put out something as close as possible to what one hears when playing back the original master tape. They openly acknowledge that these will not sound like other pressings of these recordings that people may be used to hearing. Joe Harley notes in one of his posts:
"Remember, we have our life savings in this venture. It's our asses on the line, no one else."

"We definitely encourage that [a direct comparison between a mint original and these new re-issues] Audiolab. Between Ron and myself, we have mint copies of practically the entire Blue Note catalog. As you can imagine, one of the first things we did when the mastering process began was to make those comparisons."
I will tell you that these pressings sound different from the originals. I'll leave it for you to decide whether they are better or not."
