thing here you have to understand is, they are past changes, they have decided, they are moving to development, your opinion at this point can only be to fine tune what they have planned, which they are still fine tuning.
Of course i think they should give info anyhow, id like to know what they are going with, they have already commited to it, so they may as well reveal it. Not sure why its taking so long to say what the plan is when the plan is already decided.
