Actually, there's been no news items and press of any merger or acquisition but neither of bankruptcy. As nothing's been officially announced in any shape or form, we can only speculate. But considering the American version of Yamato's website is still up and running, listing all the products that are licensed and imported from outside Japan that will continue to be sold under their former Yamato branding (the North American Yamato USA (f.k.a. Toycom, Inc.) office is said to be unaffected by despite their Tokyo headquarters changes); that Arcadia don't seem to have had any copyright issues (franchise name and merchandising); that at least the staff dedicated to the Macross series have continued with Arcadia; and that the information I got from my sources isn't the same information you got, I'm still not sure they went to bankruptcy.
