I just got an email from Adobe today it appears that Lightroom 3 is going to be in Beta Testing over the next few months... (I haven't decided if I'm going to install it yet) but I do really like Lightroom 2...
It's awesome that Adobe puts it into the community for commentary, even though their feature list is decided more than a year in advance. The community makes it better.
Its nice. I'm playing with it and LR2.5 at the same time. There is a lot of talk about it on POTN. Much cleaner integration into Photoshop and its got a really cool slide show feature that can now use music and save the slideshow as a video if you want.
I guess there are to be many versions of the Beta since they are talking about a whole new database schema but its not fully implemented yet.
I had issues with it right off the bat. It would hang up on one shot in the film strip...zoomed in. It would take some patience but it would then change to the next shot but not zoom at all. I gave up after that....though I like the watermarking.
