lol it's pretty crazy that a comment from 3 weeks ago (that MJQ found) has managed to pick up so much traction. Regardless of what Lakshya's post was meant to portray (a slip-up of groundwork on S4, hope, or just general thanks to the towards YSnet) it's started to blow up. If enough articles appear, I feel like someone, either YSnet, Deep Silver, or Lakshya themselves will have to make a comment to clarify things. I highly doubt that YSnet or Deep Silver will just come out and announce Shenmue IV this way, so I'd expect we'd get the "We have nothing to announce currently, but we are always listening to the fans" statement.
Either way, it's good press, and also lets the teams involved know that the want for Shenmue IV is there. Games Journalism never ceases to amaze me lol.
