At this stage our options are as follows:

• A. sit and wait
  That was my tactics so far, assuming that civilized and respectful behavior will ensure to get our chips as fast as possible. This in fact might have been the reason why so far our group-buy got more chips than others, at the same time with a delivery of one batch per month our last will arrive mid 2014 - ready for re-direction to the Bitcoin museum
• B. demand full refund
  The majority would be fine with getting their invested coins back and let this chapter pass into oblivion. According to Avolon's ToS, there will be no refunds. But if they really care about Bitcoin and its community and realize how much harm they caused to so many of us, they might consider playing fair and send us the coins back. This implies that you do not want your chips any more.
• C. negotiate for compensation
  While refunding all orders might exceed Avalon's capabilities, they might prefer offering a compensation in form of free chips or free upgrades to next-gen ones. This implies you would like continue dealing with Avalon.
• D. legal action
  Leave the polite arena and sue them into ground; make an example of them and put an end to the pre-order madness in Bitcoinland. This implies you are willing to throw more good money after the bad - for a very limited expectation. Your money would feed some poor lawyers and Avalon if needed will declare bankruptcy (they said they do not control the collected funds any more).

I personally will approach Avalon with options B and C for now and consider combining forces with other group-buy organizers for D if we do not hear back within a reasonable time-frame. If you have a different opinion you'd like to share, please do so either here or via PM.
