I'm bumping this thread because an Internet search for the subject line question is what brought me to this site.
If I had a 5 or 6 disc carousel blu-ray player (or, better yet, a player with two 5-pack cartridges ready to load and play 10 blu-rays/dvds), particularly if it were region-free or could be made so, I could remove at least two other components from my A/V component rack and simplify movie night considerably. Load it up with the snack bar countdown DVD, the vintage trailer DVD, the cartoon compendium DVD, the one or two blu-ray features for the night's home theater Drive-in double bill and off we go!
I remember multi-disc DVD players being a perfectly legitimate "up" selling feature on the retail floor almost from the day DVD players were available. Anyone remember the 3-disc AIWA line? Then there were 5-disc DVD players, 6-disc DVD players, eventually the 300+1 and 400 mega-changers showed up. They might have lost market share as a new "up" selling feature came on the scene; the blu-ray player.
Now we've almost come to the end of obvious new and improved features to add to the single-disc blu-ray player as a reason to sell the customer "up" for greater retail store profits. Once every blu-ray player features 3-D, Wi-Fi, Fast-Load, and a couple of other features, which direction will the brand-to-brand, model-to-model "up" selling competition go? If history is any guide, it will go in a direction that is deadly for a retail operation; "price". The competition will become who can sell the CHEAPEST 3-D, Wi-Fi, Fast-Load, etc. blu-ray player on the store's shelf. And with that, unit sales might increase for the manufacturer for a while, but profits will plunge for the retailer. Not good if you're a retailer.
If retailers are smart (and, yes, there is mounting evidence to suggest they are no longer), they'd be on the horn with blu-ray manufacturers asap demanding that they begin introducing multi-disc and other convenience features as a reason for their "geek squad" on the retail floor to sell the customer "up" to something he might not have considered but ought to consider for an extra $50 or whatever.
Like cup-holders in automobiles and back-lit remote control units, a feature like multi-disc blu-ray/DVD playback is not necessary and is a feature that must be SOLD to the customer as a reason to spend more. It's up to the seller to help generate demand for it by painting a picture for why the customer should want it. The retailer pays someone to wander the aisles and SELL these "up" features to customers, not stand there and point like a statue, right? If anything, that is where you'll find the weak link in the chain when it came to the last of the multi-disc DVD players on the store shelves. It is very possible the store clerks were so busy pointing toward the new blu-ray players that very few customers even knew why that Sony multi-disc player was priced at $129 instead of $69 like the DVD player sitting next to it.
It is the retailer who should want and demand the manufacturers provide a multi-disc blu-ray player right now. Then it is the job of the sales people on the retail floor to generate demand for that and a multitude of other potential "up" selling convenience features. It's called "selling". Since it is a given that a multi-disc player would command a higher price and probable higher profit margin for the store, it is in the retailer's interest to tell customers why they should want that feature. Retailers used to know how to train their "geek squad" to do that.
Of course, if retailers don't care about "selling" customers on an upgraded feature/benefit at a higher price point for a higher profit and would rather the direction competition from one model to another be almost all about the cheapest price then they deserve to lose out to the Internet sellers and close their doors.
