Said this in the other thread BUT! Holo has already announced ID3 and Stars EN, neither of which have debuted yet, so its unlikely that they're going into EN3 since they're a little premature, UNLESS Holo are releasing a new gen by surprise to patch over the hurt of a yab, which they have a history of doing.
My assumption is that they're going into the next Nijiwave, but mulling over the thought, I'm finding it less and less hard to believe that HoloEN3 could be a surprise reveal.
