As you found out all are enlisted. First Yonghwa than Jungshin and Minhyuk on the same day and shortly after them Jonghyun.
Before enlisting CNBLUE recorded "Don't say goodbye" (new japanese song, not to mixup with the old one ) it was released recently on their Best of album
Also Yonghwa prepared 5 songs being released as "Feel the five Y"-project ("Letter" has been released already, "Brothers" will be next)
So by selling this, the DVDs and a photobook FNC still makes some money, but it seems they don't make as much as usual. That was to be expected, right?^^ FNC tries to make BOICE and Pris familiar with N.Flying by letting NF be pre-act for FT and Jonghyun in Japan and have NF cover FT and CN songs during their own tour. NF are great pls don't get me wrong ^^
Also it is expected for FNC to debut a 2nd girl group (one girl got into the finals of Produce 48)
I think for Yonghwa's DVD you refer to Room622, right? For Japan the pre-order period is still open (Korean version as well I think, although beeing sold out already), so noone has seen it yet
Oh and Jungshin made a cameo in the drama Voice2 (towards the end of ep 8) shortly before enlisting
I guess "CNBLUE falling in love with Switzerland" is also worth mentioning (only interesting for BOICE though) https://www.youtube.com/channel/UC8p7g5Y-R4_Wj1jz74k-P2w
