He is not ignoring it. The tweet was a general response to the press tour and PAX (no idea why I typed E3 above). It is not the end of communication. Besides, I'm sure you want a response more elaborate than a tweet, do you not?
Re-reading the last line, it comes off much harsher than I had intended, so I apologise for that.
The group that are okay with BG3 now are mostly people who never played BG2.
There are actually quite a few fans of BG 1 and 2 who are enthusiastic about BG3. As the game develops we'll be doing what we can to win over as many of those as possible who currently have concerns.
