Though it's not EXACTLY the same set up of course, all these things including the AH, MH, synergy furnaces, and Aby NPCs (via the chocobo circuit) are accessible in spots like bastok mines, and other city zones. The only thing missing at this point is the ability to hear shouts concerning pick-up happenings in high traffic areas like PJ and...well PJ.

Just to drive the fact home, starter cities have linked AH's now so you can buy all the same crap that you could as if you were in Jeuno. After reading a few post here I don't think many realized that the AH's had been linked from city to city. Again, without the ability to hear random pick-up happenings, PJ will still win out in terms of where to park your character.
