What are you talking about?
LR 5.6 came out the end of July.
PS CC 2014.1 came out a week later.
PS CC 2014.2 came out, today.
What is LR CC 2014.1?
When you refer to LR CC 2014.1/.2 are you thinking about LR Mobile for Android, or LR 5.7 that'll work with the D750 and SX60 or LR 6 that will likely have new functionality?
PS / ACR 8.7 RC was just released this week as a release candidate (public beta), and probably compatible with LR 5.7, so I doubt we'll see the next LR version for a little while. The ACR 8.7 doesn't expire until the end of the year so it might be more than a month.
Adobe doesn't have to worry about generating such a big splash of a new major version to convince people to buy an upgrade, since they have cloud revenue coming in month after month, but they do want to remind people there are benefits to signing up for the cloud, so their are trying to get better integration between their apps through the cloud, as well as figure out what to do with keyboardless/mouseless workstations, like the Surface Pro 3.
