I really dig it, but I'm not yet familiar with BPG. It seems that decoding it would take more processing power, and potentially be slower than JPG. Is this the case? Under the "performance" section, decoding speed was not mentioned.

Yes, it's slower and takes more RAM than JPG. I can see a delay of about a second in my browser. (Edit: I assume my browser is caching the data, but if not, some of that time could be re-downloading the data.)

I would much rather someone revived the Fractal Image format, which is now out of patent. It's very expensive to encode, but that's nowhere near as big a problem as it used to be. It's very fast to decode, very small, and the files are resolution independent: http://en.wikipedia.org/wiki/Fractal_compression
I was blown away when I encountered it at PC Magazine in the 90s and it seems like it would be very responsive to the needs of today's web.
Its purpose is to replace the JPEG image format when quality or file size is an issue. Some of the HEVC algorithms may be protected by patents in some countries There have been some patent disputes over JPEG, but I don't think replacing it with another possibly patented format is a good idea, even if it's technically superior in some ways.
"Most devices already include or will include hardware HEVC support, so we suggest to use it if patents are an issue." I don't know if that suggestion makes much sense, but you missed it in your quote.
Even the things he does just for fun are impressive. Have you ever booted up Linux inside your browser? http://bellard.org/jslinux/
Having said that, all those demo photos do look good. I was wondering how we were going to see a demo in the browser without built-in support, but leave it to the man who put Linux in the browser to write a decoder in javascript. This is an encouraging project.
When the file size gets larger at the end, it looks like there might be a little loss of detail. Ideally I'd like to compare them by switching back and forth using the original image and the .bpg as Photoshop layers...
