Pages 1-3 are looking good.
It was announced in this week's solicits that Y would be going bi-monthly. The main reason being to allow for more time to finish the last issue which will be double sized. The alternative would have been to take a three or so month hiatus between issue 54 (out this week! Go get it!) and the final arc Whys and Wherefores and that just seemed a little too much to put the readers through.
Myself, I'm very happy about it. I've been getting more details about how this finale is going to play out and it's great knowing there will be time to give it the attention it really needs.
So excited right now.
