I saw one of these today, in our local Toys R'Us:

You just need to do what Ironworker does and paint the cockpit to make it fit 28mm scale.

And here's some cool details:
- there's a cargo hold in the back, that opens and here you can fit some minis in


- and it comes with a flying base:

Now for the bad news - it doesn't come with weapons (altough you can strap Iron Man in one of the wings

) unless you count that stupid pop-up missile launcher on top. And it can get pretty expensive, at least here in Portugal - it costs 60€!!! (for me that's almost armed robbery - i can get it for half of that, with shipping included if I buy it on Ebay.co.uk

).
You can see a review, with lots of pics here:
