It's quite a handsome valk, no doubt, but I'm already trying to complete the Hachette 2202 Yamato which is already a gonzo build in itself. I agree, for the overall total price this model will command, I do expect Super/Strike packs to be included, but maybe they'll be offered as an absurd exclusive subscription bonus. If the issues for the valk are gonna be anything like the Yamato run, then I expect the first issue to be like 300 yen, then 1800-2000 yen for next 100 or so issues.
Hachette has excellent visual guides in their instructions and videos in their Youtube channel. All in Japanese of course, but they're all very clear in what they want you to do.
Oh yeah, HLJ and their private warehouse has been great for me in collecting each issue.
