XMR can only go down. Forever.
The bears get to play until 0.9 is released. After that all bets are off. If one expects 0.9 to never get released then yes XMR will continue to go down forever.
I doubt 0.9 will result in any significant price change. The changes are mostly under the hood from what I understand Maybe if gui was released, it would increase xmr adaptation. But till then, changes to the commandline interface wont bring influx of new users, in my opinion.
Yes significantly more will use it with a gui compared to only cl.
But right now the official binaries allow very few to run it at all. 0.9 will allow almost anybody to run it. That is very significant.
What will be the result of the 0.9 release? I have no clue, what else is new

Though it won't be happening in a vacuum.
