Again instead of trying to read too much into a few vague tweets (how many times has this happened before which inevitably leads to disappointment and some cases even rage here? Lol thought we learned by now) and busting out the champagne this early like the current 'evidence' was clearly enough to go on for a character confirm it would be wiser (but not fun though) to just wait and see if TN follows up with said tweets with actually proof of x character being added into the game in the form of credible screenshots, a trailer, or even a scan.
I don't have trust issues with TN, but I do prefer having a little more concrete evidence to go on then a few twitter remarks, but hey maybe that is just me being crazy. Also TN has trolled plenty of times in the past notably nearly two months ago (so much salt thinking back) so feigning ignorance about how TN is 100% trustworthy is laughable. Just for the record I don't care if Tengu is confirmed or not, but If Ein was in the exact same spot as Tengu and his only 'evidence' for his reveal was a few tweets then I would be cautiously hopeful, but not immediately celebrate like what a few people seem to be doing already. I'm not doing that to spite them, but to spare them from further possible disappointment if TN doesn't follow through.
