While this sounds very likely and your intentions are probably good, I'd just like to say that it doesn't hurt to hope though, and you could have left it to us to be disappointed if nothing came out of it :( at least we were going to enjoy the speculation and excitement for a couple months, if they were really going to say that no physical theme would accompany the park theme. Now i'm just sad and disappointed, even before having factual reason in front of my eyes to be sad and disappointed.
A new mythical theme would've been awesome, for me. I really wished for some new fantasy - castle like minifigures and prints. I don't have the space, money or time to build actual castles anymore, but i still like to collect castle minifigs and fantasy races. This theme gave me such hope for something new. I honestly really disliked the prints and (much too bright imo) colour patterns from the most recent castle line (was it 2013-14? Red and black dragons, bright blue and white lions?). At least the last couple cmf series had two great torsoes for castle (the yellow and black ravens are sweet, and the fright knight had that plain flat silver torso that was just so useful), and there have been also some decent single minifigs from other lines, like some fire demons from nexo knights (a theme i totally disliked for everything else) or a couple torsoes from ninjago. And some fantasy minifugs from cmf. Cmf is really saving my interest in Lego, honestly. If only they didn't make all those, dc, batman, disney figs it would even be better.
I'm sorry if this comes out as a rant, i don't have anything against you, i just love lego and find it a pleasant hobby-distraction from this shitty world and situation, and was really hoping for this new theme.
