This is indeed an interesting development, with opinions all over the board regarding it...
I'm not interested at all in seeing re-releases (carded or loose) of any of the previous vintage figures,
especially if they wind up as repros like that TRU 4-pack from about 5 years ago... Didn't sell well at all, not to mention some of the more obvious concerns that people are expressing about folks who would try to pass these off as the "real thing". I don't want to see any of the current vintage market materially altered by some new influx of repro vintage figures into the market.
Loose original vintage figures being offered is fine though, as in the recent Amazon sales. Those are legitimate vintage figures, so I'm cool with that. I don't want to see more articulated versions of the prior vintage figures though. That blows their whole charm when you start messing with them with some of the more advanced figure making technology of today.
But I probably would be somewhat interested if Hasbro went and filled in a lot of Kenner's vintage line's holes, with vintage styled figures the likes of Tarkin, RFT, Slave Leia, RH Vader, Oola, Dagobah Luke, Stormtrooper Han, Garindan, etc... That would be kinda cool I think. Even if it does render obsolete some of the old vintage customs of those respective figures that I paid a rather pretty penny for back in the day...
I'm not at all excited about the idea of releasing vintage style Prequel figures though. FORGET THAT CRAP. Stick to the OT, if anything. But if these are being released in conjunction with the OT DVDs, I'd have to guess that Hasbro's going to be sticking with the OT characters here. Hopefully.
Whatever it is that comes from this announcement, it'll indeed be an interesting, if not controversial, twist to our current collections, I'm sure...
So,
MisterPL, perhaps your vintage styled figure idea that we recently discussed, will be coming to fruition even sooner that you expected... Good call!

Though I think you were mostly intimating the Prequel characters though, if I recall correctly...
