And once again... There is no more risk of this then there is of me confusing which Interceptor has Fell in it, or which A-Wing has Jake in it. People have had to deal with multiple pilots in the same ship since the game was first made. This is no different.
You can't really have Poe's X-Wing in a expansion and not have Poe. Would've it been better to include the PS8 Poe and make Black one give him +1 PS? That's comletely a matter of opinion... But having two versions will not cause any additional confusion.
Which is why the expansion should have included an alternate art card for Poe, depicting the 'Black One', and put +1PS as a feature of the Title card, with a points increase on it to compensate. The net result is the same but the execution is more elegant.
But again, they never actually said that. The fact that you read something into it doesn't actually make it true or even relevant.
Just because they didn't say it word for word doesn't mean that's not what is being suggested. The dish is the only 'change from RotJ' to be identified specifically.
