Until there's a new version of the OEB spec I don't think there's any point worrying about a new logo - there are lots of options for indicating versions, and I see no point in including anything in the first logo.
I agree with you that the logo should not contain any letters. Thanks for the SVG.

Adding the word "ePub" to the logo was also suggested, though I'm resistant to the idea of adding text that won't mean anything to non-English-speaking (or Alphanumeric-character-reading) cultures, of which there are a few.
