Saw this wave at Toys R Us today so they out at retail now too! Which means we might see the Preview Wave fairly soon...which then means there will be a good three month lull in figures
Actually, the Preview wave showing before Christmas is kind of unlikely. I think the last SW to ship is going to be this Cantina wave. I can't see them sneaking two waves of figures in before Christmas as we're only 2 weeks away. Besides, there's probably a rough street date on the preview wave. I wouldn't expect to see them before February.
Traditionally, the lull at toy stores occurrs immediately after Christmas. There will be a number of year-end sales. Then, the toy chains go into inventory mode for a week or two. Then orders go our and things start to trickle in towards the end of January/early February. I've seen it too many times to not to know what to expect.
