Just a couple of tidbits/personal anecdotes:
I ordered the Titanium Clone and IG-88 from TRU.com last week and they arrived yesterday. Much to my chagrin (and in direct opposite to what was on the site at the time I ordered them), the versions I got were the "Vintage Finish" versions. Hence, they're going right back to TRU.com, which has nicely sent me a prepaid label to send them back to them due to the fact it was a website error.
I thought this would be the final straw with me for this line until I went into Target today to see the same Bossks and Sandtrooper that have been there for at least the last 4 months, covered in dust, along with a new shelf tag that said "NCF" on it for them. Which means, "NOT CARRYING FORWARD." Meaning Target isn't getting anymore, and given Wal-Mart's glut of the same on a much larger level, I doubt WM will be getting anymore either.
I'm officially done with this line as of today, and I'd be shocked if retailers anywhere saw any of these "coming soon" figures like the Han, Tusken, Jango, or Utapau Clone. I'd say, at best, they'll wind up being HTS exclusives (if HTS can even update their site with the current wave(s) to start with). This line is, for all intents and purposes, dead in the water.
