Adobe will offer free download of LR v1.0 for RSP users. Adobe says:
1) Offer a free download version of Lightroom 1.0 for customers who bought RawShooter | premium prior to July 12th 2006, 12 noon European Standard Time. Given that Lightroom 1.0 will serve a much broader range of functionality and will be priced at a higher price point than RawShooter | premium, we believe this represents a great value for our customers.
2) Adobe will investigate to what extent your image corrections made within RawShooter can be transferred to Lightroom.
3) We will deliver support for Canon EOS 30D In RawShooter | essentials this summer.[/FONT]
