They've been releasing stuff on the site for over two years (nearing two and a half) and how much of the back catalogue have they done? Half?
Is it really realistic to ask someone to wait another two years for a small free product that *might* be considered for release? And, again, there are the free reward modules and content that may or may not be re-released.
The release rate always struck me as artificially slow. Designed to milk the "new product X is in DnDclassics!" as long and often as possible.
The really slow releases make sense for the old products that have to be scanned and OCRed and such. (Even then, getting a couple books done each day is quite possible.) And the new stuff - from late 3e onward - is all digital and just needs some clean-up and an export. Much of it was already PDFed prior to the great digital backstep of 2009.
