I would say that in terms of the wait for the PC version, 1.3 was totally worth it and I guess it would be worth it for the console. My main concern is how will stuff from the 1.3 update onwards be implemented on the console. For example Yoyos. The mouse can easily control the Yoyos and if you are inexperienced, the Yoyos can feel a bit fiddly at first but it is a nice weapon. I just can't imagine how it can be implemented but I wouldn't be surprised if 505 will do some magic especially with how they squeezed in a chock full of content for the old 3DS.
Console-wise only the 3DS version concerns me despite having Terraria on each and every device at home (ps4, ps3, Wii U, Vita, each of my 3DS/new 3DS, my iPad and my android phone). I just feel the controls on the 3DS are so tight and close to perfection though the thing that concerns me the most is whether or not a large world size will come to the new 3DS and if it can handle contents from the 1.3 updates. I just wish it has a huge world size and some quality of life changes like sort inventory or something like sort chest since it really makes things feel like a breeze.
As for release date, I will not hope for anything this year but we will probably get something next year or hopefully get 1.3 at the end of 2018.
