Wait? Yeah, you can wait...until the cows come home.
It's a foregone conclusion that ultimately both formats will peter out eventually...it's just a matter of time...like anything else.
Me? I had just both the Denon 2900 last year for a song...it was only a few years back when to get the best possible pq, diehards were modding high end Denons to the tune of 4, 5 even 6k!
So it was a no brainer for me to pick up the A3 for $200.00, with ten HD movies, and an eventual $75.00 gift card...resulting in a $400.00 player for $200.00, with 15 HD movies...not much to think about, is there? I'm not into collecting movies, or advocating the mindless amassing of DVD's and HD's, but I'd generally rather wait and see it on DVD (or HD now!

).
So, I've got ten HD movies now, will have fifteen when I next travel to BB, and I will occasionally buy others when they hit the $13-$17 range. Good movies...keepers. It wasn't that long ago that DVD's regularly cost $15.00, so it's a real no brainer in my situation.
The last thing I'd try to do is second guess market strategy or the longevity of either of these formats. They're here. The players are ridiculously cheap, and the movies are as well (at times). They're here, so my philosphy is enjoy them while they are...if you can afford it.
