Do you guys think FFG will repackage existing sets (like Laser Grenadiers and Recon Boys) to have the cards with the new point costs, or I'm just ultra cynical in thinking that they won't change a thing, so that we'll have to buy the pack of the new cards every time we want to add a new squad of pre-Seelowe stuff to out collections?

I think they´ll sell the old boxes untile they´re out off stock and then pack in the new cards...

I laminated all my cards and there´s no big problem for me to write the new costs on it, so i can keep them and can go on with using the old values too when I want to.

You don't really need to have the points on the cards play anyway. You could quite easily work your army out on paper before playing the game, I'll probably start on an army building spreadsheet now - sort of thing I like to do
