I dislike BIP100 only because it is not a long term solution and it guarantees us to have this debate all over again unlike BIP101.
Nope. Even though there is no real evidence that this was said by Gates, here it is:" 640K ought to be enough for anybody" (referring to RAM). Gavin said something similar with 8 GB blocks.
8 GB blocks do not guarantee a permanent solution. You're just speculating,and so is Gavin. Trying to predict stuff (in addition to not having solid evidence; not saying that this is the case here) is pointless as most of the time the prediction ends up wrong. The bigger time span you try to predict, the worse your odds for being correct are (good luck trying to predict what will happen 15-20 years from now).
BIP101 is the best
Based on what? Your personal opinion?

What is the "most common floor (minimum)" in this vote? If it's 1, then congratulations, you've just let 21% of the mining power dictate full control over the block size.
Wait for Jeff to clarify this on reddit or the mailing list.
