I agree that West/Lexis will still be very lucrative and continue to rule the legal research space for many years to come. I also agree that they add much value (despite competing with them, I have come to appreciate a lot of the things they do to add value). However, their operating profit margins will likely drop from the 25-30% where they now stand.
