If I remember correctly, the last Lightroom update tutorial video featured Kevin and Jeff, and they also showed an online interview with Mike, which was, as always, hilarious and super enjoyable. I imagine that Michael was not really feeling too well by that time. From that point forward, I don't recall any more videos.
This latest update looks to be major. Are you planning on a new tutorial? It would be good to have something really new, from top to bottom. Lightroom has changed quite a bit since version 1.0, so having to watch tons of videos and updates to get the whole picture seems annoying, and sometimes a waste of time, at best, since most of the features of earlier version don't work the way they do now, so you have to watch it to get the basics, then watch the updates to get the new processes, but you can't follow.
So, please bring Jeff and Kevin back!!!
