I feel like lots of modern arenas try to blend into the aesthetic of the neighborhood and area. While it is not a beautiful design, it will probably fit with the high-rises and many of the buildings around EV and the future Entertainment district. If the go for something flashy, it could run risk looking outdated fast like the Saddledome (although I love it) or Rogers in Edmonton (which wont age well). As long as it is build to have a better experience for what it's purpose is and has a better urban design than the Saddledome, than I will be happy. Even Ottawa's renders look like an arena that will blend in with the building around it, not to stand out.
Realistically, Calgary was not gonna build something crazy like they did with the Saddledome. As long as it is not actually ugly, ill just be happy people will get a better experience inside the arena and the area around it is complimentary to it. The Saddledome has got to have one of the worst concourses and bathroom situations out of any arena. Add to the fact that it is just surrounded in a sea of asphalt. I think urban design will be the most important factor for me when they unveil the new plans again tbh than how it actually looks. All the proposed designs before the last one were average at best. We will get an average looking arena, but hopefully the inside is modern and efficient.
