Christ on a cracker, people, calm the f*ck down. 

If you've made it this far into life, you should be quite able to detect the difference between marketing BS and actual reality.  If you aren't the person who makes decisions about technology then convey it to the folks that do. 

I'd much rather have foreshadowing of what might happen so we can all comment on what we do and don't like about it.  This gives MS a chance to adjust...which they do.  As far back as I can remember, they've NEVER released a major product with the exact same features as those touted years in advance. 

The alternative is the giant festival of stupid that occurs when Apple wants to 'unveil' something.
