Okay, before anyone freaks out, here's the basic concept.
I was walking through Wal-Mart last night and started to notice the immense size of some of the RC vehicle that are being sold in the toy section these days. Then I remembered that area of TRU where they sell large pedal-powered vehicles for kids to drive around.
So I got to thinking, what's to stop Hasbro from making a 5-foot tall toy of the AT-AT to be used with the 4" action figures? They set the price point at around $300. While this seems unusually high, think about how much Master Replicas is selling their "studio scale" AT-AT; over $1000 and it's only a couple of feet long.
This toy would be less than a third of that price, over three times the size, and would be compatible with the action figures (not to mention being an enormous storage case for hundreds of figures).
This would clearly appeal mainly to adult collectors with lots of disposable income (the same ones who spend thousands on their costumes and buy up hundreds of dollars worth of prop replicas a month). But it would also be one of those things that kids dream about owning all the way into their adult life.
While it seems unprecedented, remember the USS Flag aircraft carrier for the GI Joe line was over 7-feet long.
A 5-foot tall AT-AT would be a huge draw to the toy section, just because of it's impressive size and it would go down in history as one of the greatest Star Wars toys ever made.
And if it does well, we could get a 4-5 foot diameter Millenium Falcon released after that.
Of course, you'd probably have to sacrifice a large piece of furniture in order to find a place to put these, but that would be a small price to pay for greatness.
