I hope so for your sake, but they always use the architecture as the biggest reason why backwards compatibility isn't possible, and if that truly is the case then it wouldn't make sense that your digital download titles would still be working.
For digital download titles it's less of an issue vs disc based games. Reason being that the games on the discs will be the PowerPC RISC architecture games' data files while the digital download versions would be whatever you end up downloading.
It's worth keeping in mind that very many games for both the Xbox 360 and PS3 exist as PC versions as well. 'Porting' those games over to the new consoles would be far less of an issue than having to completely re-launch disc versions of previous-generation-console games for the new consoles.
If you already own the game on your 'account' and can only be logged into your account on one console at a time anyway, then there shouldn't be much, if any, reason for you to be unable to play that game on the new consoles aside from publishers' greed.
I'm not happy with the Xbox One,not at all.This whole thing about pre-played games and lending games is so stupid.One more reason to hate Microsoft.
You're hating the wrong people. You should be hating publishers, because it's up to publishers to determine whether or not they want to have a tax applied to the sale of used games and whether or not they want to have a fee associated with lending out games.
There are very good reasons for these two systems to exist, and they could benefit gamers more in the long run than I'd wager you could imagine. All people like you are seeing in the short term is "I'm going to get less money for my used games" and "I'm going to have to pay money to borrow games". Never mind that when you lend out a game to a friend, particularly in the case of single-player only games with limited or no replay value, the publisher often makes absolutely nothing off of what you'd just done. Likewise, when you sell a used game to someone, the publisher is losing out on a sale of their title entirely, and every subsequent re-sale of that used title is another lost sale from which they could have made some profit.
It may sound like greed on the publishers' case, but if this system were to be implemented there's a very real possibility that they will bring down their games' base costs to more reasonable figures to make up for the deficit.
As it stands, right now publishers make an absolutely disgusting amount on a per-copy-sold basis, but have to make that much to accommodate the lost sales on their games that get resold as used games or lent out to who knows how many people.
Can you imagine how many more games there would technically be available for people to play, and how much more likely they would be to buy a copy of their own if games' prices had to be slashed in half or be brought to an even lower figure? We might see more content developed for games and more IP generation thanks to publishers not necessarily needing to be as concerned with creating a product that would only satisfy a niche market, but that has to be priced accordingly to other games they publish just so people don't (wrongly) start bitching about this game being so cheap but that game being so expensive.
As far as I'm concerned, games like Fable 1-3 shouldn't cost more than R150 at launch in South Africa, because they have limited to no replay value and are single-player only. A game like Demon's Souls on the other hand has at least some kind of multiplayer and so could be slightly more expensive for the more expansive gameplay potential it offers, at R200. Then a game like Calladoodie, which has immense persistent replay value could be priced at R300 versus its current R550-R650 launch price - because it has both a single-player campaign as well as greatly replayable multiplayer content. If it cost just R300/title versus its current cost, just imagine how many more people would happily go out to buy it.
