Good idea about the A330 aircraft retirements. I don't see the negative side of putting your name down for the 777 though. I believe you can always take it off up until 3 months prior to your transition, so that might give you a bit of time to further consider your options.
Then again, I suppose the problem with everyone putting their name in the hat might signal to fleet ops that this policy is something other than a result of the foolish policies in place over the past 2 or 3 years.... specifically DEC's, no proper transition upgrades, and a total lack of regard for seniority.
It should be another interesting year at EK.
