Price of PCs as Vista nears?

I'm in the market for a replacement laptop and I'm thinking that as
release date gets closer ( especially around winter holiday time) that
XP PC's will be VERY low in price to clear the shelves for Vista PC's .
Come the Vista release, those pc's are boat anchors for retailers:
especially Dell with their Intel only platform. I know they only build
to order, but they ( and others) need to be selling SOMETHING for those
last few months. So they'll have deals and others will match - esecially
on NON Vista capable PCs, and that Nov/Dec will see some super deals for
folks that DON'T need Vista. I can't imagine that someone that DOES want
Vista is going to buy a PC in November and then wait for Vista to hit
the store shelves ( will it be there in January ? February?) and THEN
pay $200 for it, bring it home, try to get drivers, then format his
drive (that he has used for 2 months) and start the install of Vista,
his apps etc. It would/will be a disaster ( and void the warranty ?) SO
they'll be a time when it will be tough to sell a PC with XP. I know
the manufacturers COULD just take them back to clear the shelves, but I
think that some buyers will buy the older technology at a good discount.
I think especially the 32 bit boxes will be very cheap and Pc's that are
NOT Vista capable. So, to bring it back to my reason for this ... I'm
looking for a deal to get the higher requirements -video, 1gb of memory,
etc included and most notebooks DON'T currently have that unless
ordered from factory. Do you think I should wait and maybe get a beefier
notebook offer - to make it Vista capable - even though I'd just use XP
?

Your thoughts - will we see great deals before/after Thanksgiving this
year ? on only low-end 32 bit PC's ? Or across the entire line ?
