MG Astray Red Frame?

Well, just read it in some blogs...it is said that Bandai will release MG Astray Red Frame Kai next February.
There's not much info about this model kit, i still don't know what that 'Kai' means. Maybe it's a 2nd revise like Blue Frame or maybe it's like an additional equipment.
Whatever it is, I just can wait and see while saving up my money. And i hope they will not release another my favorite gundam model kit in the same month....
