I agree that the counter is very irritating and should be removed to avoid idiots getting confused.
However, the counter was intended to mean that there is no clear ETA, because the time it takes until the new client is ready to be released is not simple to calculate.
Furthermore, all those conspiracy morons who say "There is no ETA, plus the ETA has been extended twice, that means it is very likely that Spectre is never going to be released/is just a lie to get money" can please fuck off. This forum doesn't need cancer, and if you still maintain that opinion you probably don't need this forum any longer anyways.
Edit: In the developer chat we get enough frequent footage that I can certainly say Spectre is not a lie, and it won't be delayed for a very long time neither.
