It also looks like the "high definition textures" people talked about in Beta didn't make it in either.

Those textures have been in the game for months now. They're only visible during conversations, though.

Investigation and slicing actually. Read.

You're using outdated information. Beta observations and more recent developer posts reveal that most rare schematics are found using Underworld Trading.

It's only a rumor. They're letting players into the game as quickly as possible; if there are no hiccups you might even be invited by the 15th. That said, the advertised early access period was up to 5 days, meaning 5 or less. Even if you were to get only 1 day of early access, they will have still fulfilled their promise.

Thanks. I was thinking slicing for the rare schematics as well as creds. Now I'm not sure though. Rubat is probably gonna be cheap and easily accessible. The other stuff maybe not so much.

Most rare schematics are part of Underworld Trading, not slicing.
