Does anybody here know any play testers? I assume that they get cards printed that they test with, but are not yet final. What sort of symbols and/or numbering are on those cards?
Such a bland generic symbol sounds more like a play test set than a production set (in which case I wouldn't read much into the numbers either).
Either way, as Damon has said in the past, printing a new core set is a big undertaking that requires buy-in from many people higher up in the Asmodee/FFG chain. If Damon and team wanted to print a core 2.0, I suspect that they could start re-balancing and testing long before they got commitment from the business to actually print and sell core 2.0.
So my hypothesis is: Core 2.0 could be in development, and even be a fairly mature product, but still be a long way from guaranteed to make it to shelves ever (much less soon). In this hypothesis, rumors may be true but still never come to fruition, and we wouldn't hear anything official before the product was sent to the printers.
