The final version of Lightroom 4 appears to be available on the Adobe website. This is a much quicker transition from beta to final product than has normally been the case with Lightroom. The list price is $399 - in line with earlier versions - but it is on sale right now for $149. The upgrade price is $99. I say appears to be because there are a few odd things going on on Adobe's redesigned (and slightly irritating) site. Choosing the upgrade option takes you to a dialogue where you can select from a number of options, but the option for identifying your current version runs off the side of the dialogue box and (on hover) only specifies upgrade from Version 1 or 2, with no way to select version 3 (at the moment). Also linking to the 'try' page brings you to a page that manages to list both version 3 and version 4 as the trial product. Hopefully Adobe will sort this out soon - I particularly hope that that upgrade problem is only a layout problem and doesn't reflect a decision by Adobe to permit upgrades only from LR 1 and 2. That said, I suspect it might be deliberate. I can't think of any other reason why they would offer the full product at only $149. Those of us who are dedicated Adobe LR users, having already sampled LR4 through the Beta will be getting LR4 either way. Adobe knows this - so they have us over a barrel on this one if they choose.
