I just don't think it gives the best impression. It certainly doesn't, to me.
On one hand, we are effectively told "we have a new machine out in a couple months, you should look into buying it" (That's great! Well...Show it to me, then!)
But, on the other: "and, at the time we have a huge opportunity to impress and express the appeal of this machine to a key audience, we're going to instead host a closed presentation to select individuals, and not manage the interests of the worldwide informed audience, whom we may have grossly misinterpreted, evidenced by a rocky E3 showing."
But, hey, you'll buy it anyway...We're counting on it!
Even though the show has yet to begin, that's just a poor initial impression, if the opening headline reads: Microsoft did not hold a public-facing conference, unlike their major rivals - and, yes, I'm including EA in that description. As ever, we'll see what takes the place this week, but, right now Microsoft still doesn't look all that strong. And, certainly doesn't put forward the appearance of a new platform curator, confident in the strength of what they're about to push, and eager to make sure the world knows it.
