Because of Delays there are no 'new' books this week. In case you didn't already know, Daken: Dark Wolverine #5, which was originally scheduled for today, has been pushed back until February 2. Also, next week's X-23 #5 is now going to be released on the following week of January 26.
That being said, if you want to catch up, this is a good time. Marvel is releasing, Marvel Must Haves for both Daken: Dark Wolverine and X-23, as well as the main Wolverine series. What these are, are collections of the first three issues of each series into one giant-sized issue. X-23 and Daken: Dark Wolverine is going for $3.99 and Wolverine is $4.99.
This is an economy-friendly way to hop onto these books if you're not already on board. As for everybody else, just pull out a good old Wolverine trade and wait for next week.
