I've been an Adobe subscriber since CS6 came out so have 1st hand experience of how it works.
I pay a flat fee of £17, incl. tax, each month for a standalone CS6 subscription. The standalone full price of CS6 in the UK is in the region of £700. I could not justify the cost of the full standalone boxed CS6, so was happy to be able to take up the option to get a Photoshop subscription.
When Photoshop CC comes out, I am eligible to upgrade, with no change to my monthly subscription fee - subscriptions are based on a calendar year from when you 1st subscribed.
That's the point a lot of folk are missing - you are subscribing to Photoshop, not a specific version, as under the terms of the subscription you will always have the latest available version of the software.
The cost of the subscription is no more than it would be if purchasing the products as boxed versions under the traditional upgrade cycle - the difference being, you won't need to purchase an upgrade every time a new release comes out if you want to keep your software current.
As for LR, Adobe say they have no plans to make it subscription only.
