I imagine they are watching to see how many views it is getting to see it a dub is worth the cost.
IDK - If they've got the license, it shouldn't be any more expensive then the other stuff they do on a regular voices as they use (and still have) the same group of VOs they used for 2199 and 2202 - as I hear them on all the other Dubbed content I watch on Crunchyroll.
And to me - the weird thing is, CR isn't even doing much promotion that they have it (I had no clue until it was mentioned in this thread yesterday, checked and saw what many others did - Ep, 2 was the only one showing, so did a Google search saw the one small blurb from Crunchyroll (again not alot there and no real info other then: 'and other episodes when they are available....')
IF CR did spend a lot of money for the license - you'd think they'd promote it with a bit more fanfare because even today, SBY is one series the still well know outside of strictly Anime fan circles.
I get that perhaps it's because the Japanese release is following the SBY 2199 theatrical release cadence, (way back in 2012), with the first 2 eps released on 7/19/26 followed by 4 episodes to theatres each quarter over the next year (Eps. 3-6 are slated for November from what I've read); but yeah, if they have the license, they should continue with the English Dub process (IMO)...I mean hell, they did English Dubs for crap like
Strike Witches which had a similar break between the various series releases from what I saw.

(I also hope them having 3199 means they got 2205 too, and will be putting that up at some point - hell, the events are referenced in the 3199 opening credits.
