One of the things I like most about Impressions is that it's old, a leftover from a different (better) time in Epcot's history. If it's eventually getting refreshed, I hope Disney doesn't botch it.
Re: that view of the showbuilding from across the lagoon... are we assuming the building is going to be themed on the side facing the lagoon, or will more foliage be added to cover it up? It seems quite a bit of the foliage buffer has been removed to facilitate the construction, and I would hope they'll add back as much of the lost density as they can.
