Fairly Certain
Without going out on a limb, I'm fairly certain that as far as the Team Website is concerned at least for some reasonable period of time the benchmark stuff will remain posted. But as "redaxe" noted Phase II with the BOINC platform is going to be a new ballgame as far as any of us can tell. I have not seen any information to indicate that there is going to be any way to reliably compare performance during Phase I against performance in Phase II.
My current limited experience and the fact that I am spending every moment possible searching out and reading everything I can find from others with experience, is not producing a lot of exciting results concerning the outlook for us "stats junkies". Certainly at the very least there is going to be a dry spell stats wise until the rollout is done and things mature and third party developers begin to introduce some utilities with which we can once again start producing some interesting and informative numbers.
