A source called it "the same type of deal" the group did last year. Whether that means the mansion and all the perks that went along with the workouts, we'll have to wait and see when players can be asked about it in a couple weeks when training camp begins (Report day is July 22; the first practice is July 23.)
A QB getting together with his skill guys isn't unique to the Cardinals by any stretch, and in fact it seems almost necessary in this day and age. There were not a lot of personnel changes in that group, so the improvement Murray and his pass catchers want to make will be incumbent on ratcheting up performance instead of adding new pieces. The more chemistry that can be sourced with work like this can only help.
