I was not too thrilled when 21c announced the F-4 as it seemed to be unorigional and a way to undercut Admiral Toy's hard-won effort, however...
A B-25 is friggin awesome 
I will definitely get one of those and expect it to be the coolest 1:18 plane to date! There are lots of aircraft versions and plenty of neat paintschemes that 21c can do with it! My wish is that the first will be a B-25J with the glazed nose, turret behind the cockpit and the tail gun that has the little "canopy." This plane had also better have a full interior and come with crew figures! Save the gunship version for the subsequent S2 release.
My only potential concerns are the QC issues. The Avenger seemed to have alot more than the smaller 21c planes: missing screw covers, paint scuffs, misprinted markings, broken canopies, cracked & misglued parts. Those defects were in part because it is a large and complicated model and was packaged in a way that it shouldn't have been. The B-25 will be even larger and more complicated than the Avenger, but at least won't have loose folding wings! 21c had better up the ante with the overall QC inspection... Oh, and hopefully these will go to the
small retailers first rather than just a few select Wal Marts (that get 30 at a time and then practically throw them away).
21c is taking a giant leap forward with the anouncement of this aircraft and I hope they make it the all-round best release to date in terms of overall production quality, detail, and value! I'm eagerly awaiting further developments on this release
