They've remodeled the F6F-5 so it's a better than average chance we'll get the F6F-3 (remember when the Hogs were redone they didn't announce the F4U-1A until the release notes when the patch came out).
So how about a remodel of the Wildcats while they're redoing the Big Grumman (and add the F4F-3 as a distinct ship from the -4 for good measure)?
