I've been thinking I would go premium (assuming the art package isn't completely awful) but after watching the stream I'm leaning more towards the pro. I'll want to play a premium/LE before deciding for sure but based on what I saw even though the additions are great, I'm not sure I can justify the additional expense for premium.
Regardless, I love the game and am looking forward to getting one. Sure it will be great whichever version I end up with.
