Just because they promised doesn't mean it's an unbreakable oath they have to follow up on. AL are a business first and foremost, putting out a film that no one at SLA liked in a wide release, which would likely bomb due to negative word of mouth, then I don't see why they'd opt to potentially lose money. Same goes for Geass, if the appetite was there for the first one, they'd probably get the other two, but if few people went to see it, I don't see why they'd put the other two on when the returns are going to be even fewer, it just doesn't make no sense.
Also, no one is forcing you to buy anything. Standards on release would be ideal, sure, but one of two things will happen. Either the CE will bomb, no one buys it, the price comes down in a few months, you can get it cheap then, or the CE does gangbusters, sells out, and we get a cheaper SE down the line. The only thing that's working against you is patience. The attitude that is perpetuated amongst anime fans that they have to see the newest thing the microsecond it comes out is irksome at best and down right obnoxious at worst. Patience is a virtue, and if you wait long enough to see this film that isn't supposed to be much good anyway, you will be rewarded with a price you deem suitable.
