To some extent, investigative reporting is necessary because we don't have video of all the events. As video recording becomes more and more pervasive, it will become less and less likely that a crime or the immediate surroundings were not caught on record. Of course, criminals will go out of their way to avoid recording (as according to the author's fictional crime series, The Wire, they avoid cellphones), but only criminals and privacy weirdos will do that, and there are a lot more criminals than privacy advocates. Of course, some investigations will still be needed, but even if there are currently no investigative reporters who blog as their primary outlet, other types of reporting has successfully made the jump. I couldn't find him in google just now, but there was a blogger from several years ago who was embedded in Iraq and made his living off of his blog and occasional freelance stories sold to other outlets (newspapers? Dunno). One objection to this might be that governments will just legislate against cameras recording their workings, which they're already trying, but in the long run, as cameras and other recording devices get smaller and become more integral to everyone's life, this will have no more effect than Canute's courtiers' plans to roll back the tide.
