I kind of hope the Dagobah Luke has some sort of interchangable head/arms too, but it is hard to tell.
I'm really thinking that Hasbro's going to get this one right for some reason - maybe 'cause they've been restoring my faith of late, and proving to me that they're listening to what we really want. If this does wind up being a one-pose wonder, it'll still be a very cool figure IMO. But I'd obviously like it to be able to work both ways, and I really think it will...
There's two options here that Hasbro may go for. One, it looks like this is going to be one of those "ball jointed" heads that we've been seeing lately, which you can actually just pop right off of the neck "stick" quite easily. So with that in mind, it'd be very easy to make this Luke have interchangeable heads in that respect. The question is whether Hasbro would want to include another loose head in the blister, which might look a little wierd/freaky to some people. But definitely do-able. I suppose they could do the same things with his arms as well, like a couple of the C-3POs we've gotten in the past. Perhaps the apparent lack of any other accessories with this figure, lends itself to some of these interchangeable body parts as the accessories instead...

The other option is just for a dual-release type of thing, ala the head swapped RFTs and IOs we got last year, or the newer Dignitary/Outlander Club figures that shared parts recently. Yeah, it'd be a little strange to be buying two different Dagobah Lukes so close together, but I'd definitely do it to get one in the "force pose" and a seperate one in a neutral stance. That'd be A-OK with me too!

But even with the prospect of just one-pose, this figure looks awesome. I'm a little disappointed that we don't have any of the boxes or gadgets for him to levitate, but I guess I can borrow some from the Dagobah X-Wing. And like Ed mentioned, I think with the inclusion of the backpack with Yoda, there's definitely got to be a neutrally posed Luke coming somehow...
Does that Yoda have a repainted Episode1 Yoda head?
That's kinda what I was thinkin' too, Ed.

The rest of him looks great, but I really hope they get his head to look a little better, 'cause I definitely don't want to be reminded of one of the inferior Prequel Yodas when I'm looking at this OT version...
The Holographic Ben looks great too! I wouldn't mind a little blueish tint around the edges somehow, but other than that, I'm digging their new approach to Ben's spirit. Makes the old blue one look down right stupid!
R2 was pretty much exactly how I was hoping he'd be - all yucked up with heaps of mud and grime. I like that they're not just spraying it on like the atrocious one that came with the X-Wing, but rather applying it in a much more realistic manner. Hopefully they'll also toss in with R2 a few of the boxes and gadgets that Luke levitates.
Cool connecting bases as well. Great wave all around, but the potential to be really incredible if Hasbro gets some interchangeable parts on Luke, and a new Yoda noggin too!
