Interesting, John. Of course, we can expect the publishers to respond in this way because of their fear of losing market share. However, they've become fat on the proceeds of scientific publication as a result of being just about the only industry that gets its raw material free of charge. I don't understand why the universities don't go further and collaboratively publish free, peer-reviewed e-journals. In many small fields, like information science, for example, it need not be very expensive - as Information Research has shown - and I don't find anyone arguing that the journal's standards are lower than those of the print journals.
As for, "Is 'access' winning the battle over 'acquisition'?", I think the answer is probably 'Yes' and the trend is gaining strength as authors in particular learn that they have nothing to lose by demanding open access for their work. I expect the trend to continue and strengthen.
What do the 'lurkers' out there believe? :-)
