For context, the numbers are around 68% Common, 20% Rare, 9% Epic, 3% Legendary on 26 of the 30 picks. The other 4 picks are 'Rare' picks that have a chance to be upgraded to Epic or Legendary at a slightly higher rate. Flamestrike is 50% less likely to show up refers to it being 50% less likely to show up in terms of cards of its type. For Flamestrike, its definition in terms of the draft tree is ClassCard/Spell/NotMostRecentSet. Meaning cards that share that definition will show up around 50% more often. Abyssal Enforcer is defined as a ClassCard/Minion/MostRecentSet, so it will show up ~50% less than cards in that bucket.
As a further note, rares and commons specifically have a very similar chance to show up on a card by card basis. What I mean by this is Commons as a whole show up more often that Rares, but any individual common will show up about as much as any individual Rare (or close to it). This means you should see a similar amount of Blizzards to Fireballs. This is a little strange so I'm curious what the feedback will be on it.
Talking about the exact chances to get any particular card could be a blog on it's own. Each of the classes vary slightly because of the differences in #cards available and minion/spell ratio within each rarity. I recently asked a bunch of friends (who very, very heavily play arena) if they had an idea what the current ratio of commons/rares was and they had no idea. Makes me wonder how necessary a full report on that kind of thing is. In any case, I'm happy to clear up any outstanding questions you all have of the new system. The blog post for this was not the place to go over 100's of numeric details.
Rare Card Bucket 20% of times in 26 of the 30 picks means that during non-rare picks (1,10,20,30) a rare pick happens ~20% of the time. Sorry if that wasn't clear, it is unrelated to a programming statement.

Yes, new. I'm not at work yet so I could be slightly off but I'll re-clarify once I get there :).

They will remain out. Will be willing to remove or adjust if balance is out of whack, yes.
Iksar
They are at pick 1, 10, 20, and 30. Nothing has changed in that respect, it's been like that on the live environment for a very long time.
