That doesn't mean they discontinued GT. Studio still exists and they may be working on a GT7 or not, but even if you don't like GTS, consider it another game or doesn't sell much doesn't mean it was discontinued.
Didn't say I "know" its discontinued. Just saying it seems that way. GT6 came out 5 years ago and we haven't heard anything about GT7 yet.
There's no need for more than one Gran Turismo per generation. Same with MLB The Show, or any other sports/racing games. These should come out once per gen and then have continued support and DLC packs for the rest of the generation.
OT: Sony seems to be going a certain way with their studios which seems to be the exact opposite of the direction MS is taking judging by the studios they've acquired. From what I can see MS wants a steady stream of small titles to keep people subscribed to gamepass to check out the next game, none of their studios can be considered a great developer who's going to put out a GOTY contender. Sony on the other hand is nurturing their studios to put out generation defining titles even if it means they make only one or in some cases two games per generation, they essentially want each other their studios to be on the level of Rockstar or CDPR. So far it seems to be working too, they seem to put out GOTY contenders pretty much every year (since 2008 the only year Sony has not had a game in the top 5 GOTY winners was in 2014) and the sales of their games have skyrocketed this generation as well. If they can put out two games on the level of God of War and Spiderman every year then yeah they don't need more than that. Especially considering we know they're doubling the sizes of Guerrilla Games and Santa Monica so they can work on two full productions simultaneously, and they have a new studio in San Diego. Perhaps do the same with Naughty Dog, and Suckerpunch and they'll be golden.
