I'm sure BlackMagic Designs will be very happy to sell you their cheap desktop cards as monitoring options :)
IMHO, RED Rocket™ is a temporary fix. I talked to my friend at nVidia last week (on the direct compute team) - he was surprised that they don't have realtime GPU decode yet. And with a dual 6-core 3.3ghz Nehalem - CPUs should be able to decode faster than realtime the moment someone gets some decent multithreaded code going.
BTW, in a few months' time - do you really think Red will sell a 2/3rds "consumer" Scarlet - and tell everyone to buy a $4000 card to watch it in realtime in full quality?
If they do, they will get hammered in the reviews because reviewers and consumers won't have a rocket. They will try to play it on their desktop and will say "we can only view it at half res debayer, and it's grainy"
In order to avoid this, I am certain RED will make sure their code is multithreaded soon.
To me RED Rocket™ is a cool thing for people who want to monitor at 4K. For normal finishing, HDTV resolutions, it should not be necessary.
So yes, I do not see a need for RED Rocket™ if you have more than 6 months' patience.
