I think that over the next 10 years, more old newspapers will come on line, especially some of the long lost off our streets, more Parish Records will be available on line and my big wish that the GRO will find some way around the law and issue certs. on line.
More of the records held in county archives become available online, and the LMA releases more of its extensive collections online.
Although I sincerely hope that you are right, I wouldn't like to take a bet on it

When you are in a library, you can whizz through microfilms to find what you want, but you can't do that on a computer online. To be able to access stuff online, it has to be digitised, indexed, transcribed, and stored, and all these things cost money. The records on the LMA pre-1813 are very difficult to photograph and transcribe, because of the condition of the originals. I'd love to see local newspapers online, but unfortunately these would also need to be digitised, transcribed, and cross-referenced, which again would be time-consuming and costly.
Your suggestion re the release of online certificates specifically for genealogists might become a reality - the government are looking for new ways to make money, so this could happen if it can be proved to be profitable. I'm not sure how much of the GRO's revenue comes from private family tree researchers.
