Not getting a response to questions about the D:OS release one weekday after the Collector's Edition was announced is hardly grounds to assume Larian suddenly figures current customers are disposable.
Very true, although honestly this should have been handled better.
If it was just a collector's edition, the amount of time it's taking to get a response on the CE questions wouldn't be a big deal. But when you put a limited edition CE out there for sale and essentially saying
"act fast, only 1500 are available!", you should probably plan on getting a lot of CE questions answered that same day.
Better still, have a FAQ with the answers to these (fairly obvious) questions ready to go the day you put the CE on sale. It's not like the announcement caught the studio by surprise, they've been talking about it now for the better part of a month.
I suspect people will be even more annoyed (and understandably so) if the questions aren't answered before the 1500 CE's run out.
