When I was at Local Wal-Mart Number One this morning, I noticed that they had one of those "aisle endcap" things (not the whole endcap, but the things that hang on the sides of the endcap with actual pegs) filled with MORE Greatest Battles figures, and the price marked above the 10 pegs filled to the brim with more Threepios and Padmes and (strangely enough) a rather sizeable amount of Shocktroopers was $7.59. I thought this was a little odd, since the regular section had the price at 6.62 (which is what it's been for months now), so I scanned a GB Threepio (plenty to go around) and sure enough, it was $7.59.
If this is a fluke occurrence, then that's one thing; if figures are, across the board, going up to over 7 bucks (Episode I figures didn't even get that high), then I think we can kiss the line goodbye in the next year or so if Hasbro doesn't make a conscious effort to increase quality over quantity.
Half an aisle down you can still get the much more articulated Marvel Legends figures which often include those "Build a Character" pack-in parts and a comic book for the price of a SW figure. But I guess now that Hasbro's doing those as well, we can expect to see 1000 Wolverines and Spider-Mans with "awesome 12 points of articulation" and no pack-in build-a-characters.
