There's going to be two Captain America titles - one taking place in the modern day with Steve as Cap and then the other taking place in WWII with Cap and Bucky.
This goes right back to the "too many titles" thing being discussed in the other thread. Why? Hasn't Brubaker pretty much got everything out of WW2 Cap that there is to get? Those stories work great in context with what's going on now; a separate book is overkill. If you feel like you have stories to tell, tell them as add-on stories in the regular Cap book like they've been doing with that mind-numbingly boring girl sidekick.
