Denon DVD5910 1080p upgrade? anyone have it?

The Denon does only 1080i as it is.
The 'new DVD-5910ci does 1080p.
An upgrade is available via Denon (for $300) to upgrade the DVD-5910 to the DVD-5910ci so it too has a 1080p output.
So THAT is the question: is it worth $300.?
I only PAID $1,800. for the player locally, The dealer had FIVE in stock and was desperate to sell them!! So $300 more is, well, more! not like I had the cash for this thing @ List $3,500.!!!!!)
I KNOW no TV's now accept any 1080p input, but pretty soon they will... And I want to know if it is worth blowing $3small on it. (I am CERTAIN that this upgrade is a very 'limited time' offer from Denon. Three months from now I will just cry because it is too late, If it is worth doing.)

Actually some current sets have 1080p inputs.

Considering that native DVD resolution is only 480p at best I guess I don't see the point.

I would not do the upgrade. It will be upconverted to 1080P. IMHO good 1080I/60 is marginally better than good 480P/60. I think the diff would be too small to worry about. Also someday (hopefully sooner than later) we will have true HD 1080P in Blue Ray and/or HD DVD. These players will have a phenomenal HD pq and probably a better upconverted pq than the Dennon for probably close to the price of the upgrade your speaking of. You can already buy the Toshiba HD player for under $500.00. I owned this player for a short time and the pq was outstanding on my 133" diag screen unfortunately it had a few to many bugs that need to be worked out so I returned it. As soon as the bugs are remedied I will pick another up but Im really hoping for a combo player. Another factor is your display size. I personally do not see a ton of improvement in upconverted pq until about the 60" size. Hope this helps.

Thanks Braro,
I just do not think the hi-res formats will take off.
The Denon for me,is so I have the 'top of the line' DVD player to play DVDs.
Certainly in five years the hi res may be sorted out, and a player would be in order. But they would NOT play a standard res DVD better than my 5910.
I have a Pioneer LD-2 Laserdisc player. The output sucks comepared to DVD, until I turn on the Sony Plasma 4x density, then the LD's look pretty good. (The severe grainyness is gone!)
And I suppose in a few years I would get a 60" 1980x1000 pixel tv with ...?
Anyway, the Denon does a god job now, and I hope will continue to do so for the 600 DVDs I have no plans on replacing with Hd or blu-ray
(like the 100 or so Laserdiscs that I can't replace with DVDs. I keep two LD players around. The LD-2 and a 3070.)
