This is just something Disney does. Toontown is also in the same situation. They have a new significant content update about once a year. They do exactly the same things you mentioned with Toontown also, how many times have they said Speed Chat Plus would be coming the next month when it really wasn't? This is Disney's style of doing things so if you don't like it; find another game(No offense Intended, I think this is the message Disney is conveying
).
