I've been a PS user since version 4 and a Lightroom user since v 2. I am up to date on both (Cs6 and LR4).
Right now I'm really questioning whether to continue with Adobe.
I'm concerned about a company failing to continue support its products, about proprietary file formats and being locked into increasingly expensive subscriptions (far more costly that upgrading and that will probably become worse!), about being able to use the product while traveling but offline, etc.
This decision to end support on existing products makes me mistrust Adobe.
I'm already wondering what the alternatives are!
I also recall that Adobe had a 30 day refund window. If you were in that window for Cs6, would you return it and spend your money on an alternative product?
