Hi Goose,
I am copying this post to the NEW FORUM (models.rokket.biz/index.php)
I think it's inevitable that revell will re-release the Gato with updates, but probably much liek the VIIC/41. The present kit is a good POST war boat, and needs some important mods to ake it WWII (IMHO). I see your point about waiting, and it is probbaly smart, even if Revell wimps out or somehow fails to deliver as much as is expected. certainly no harm.
There are a lot of improvements and custom bits possible, all coming in the future somehow!
