Is the book going to stay in the present time or is it going to be bouncing back and forth between the two groups?
I have absolutely zero interest in the old thunderbolts anymore as this time traveling arc + no more juggernaut + hardly any Cage ruined the book for me. I got intrigued by #175 and the Dark Avengers (SKAAR! plus Cage) but then I see #176 and it looks like it is going back in time again.
If it is going back and forth, I want no part of this book.

I'm guessing you only joined post-Siege?
