A Scant is a small amount, and I say that waiting til the end of April is more than a "Scant", but the sooner the better. Just wish they would announce at least a perspective date.
I would be happier with a (*Subject to change) date and give us some idea. Having Moto say, "We would like to release the Bionic the week of XXX" and just keep us up to date with any problems they have that may push it back would be much better than one "End of Q1" announcement months ago that they have no plan to hit now.
You bring up a really good point.
I do see this as a better idea, but look at the kind of problem it got the Thunderbolt. It was all set to be released in February, then a major problem with the battery occured, and now, for some reason, it's delayed until this month.
Now, monkeys(and by monkeys i mean corporate baboons, er buffoons) tend not to like it when they are told that they might get a banana by a certain time. These monkeys will then retaliate in anger and start throwing stuff if they don't get their banana. Also, if they are told the banana was delayed because it was spoiled, the monkeys will not want the banana once it comes out, as it is a bad banana.
I use this analogy to represent the majority of the human culture, and mostly the united states. If people used common knowledge and logic like you and I do on forums, I'm pretty sure we'd be getting more ETA's. But, alas, we don't, because not enough people do their research and try to understand.
TL;DR:
If you learn, you deserve ETA's. Otherwise you're hosed.
