RPG's are dying.
Evolving implies that it is retaining it's genre, while adding to the previously used mechanics. Fallout's and Baldur's Gate's addition of NPC party members with personalities was evolution, BG2's romances was evolution, the shift from Armor class to Damage Resistance was evolution.
Making a Shooter(ME2) or an Adventure game(Oblivion, Skyrim) and calling it an RPG isn't evolution, it's mislabelling. They all lack the qualities of an RPG, and embody the qualities the other genres are defined by.
RPG's are dying, being replaced by Mass-Market games for people who want to pretend they're RPGers, but actually hate RPGs. This very board illustrates that quite regularly, with people claiming Self-insertion is an RPG, and often giving definitions that make Super Mario Bros an RPG by following the logic.
The reason for this is simple, the publishers are severely over-extended and in danger of bankruptcy. Specifically EA and Zenimax.
EA spent nearly 800 million buying Bioware, and tens of millions more on Star Wars development. But Bioware's never been a sufficiently heavy hitter to warrant 800 million, flipping through sales figures shows they have don't usually break 5 million copies with their games. EA paid for Star Wars, not Bioware. Bulletstorm underperformed, DS2 underperformed, DA2 bombed hard, so did Shadows of the somethingorother (Selling only 24,000 units). Then they turn around and drop nearly 1 billion on Popcap, years after Bejewled and Peggle ran their course. Meanwhile, they're using some creative accounting in their quarterlies, reporting units shipped to stores as revenue, which they stand a good chance of having to take charge-back on. EA's spent too much money, and had too many underperformers, to be comfortable with anything that isn't aimed at "Mass market".
Zenimax is no better, spending huge amounts of money buying studios left and right, with only Bethseda releasing games. ID isn't relevant anymore, Fallout underperformed badly, Fallout NV was sabotaged by Bethseda forcing it to ship early. Meanwhile Zeni had to borrow money to make their purchases, they can't handle a run of failed games.
So what do they do?
Aim everything at the mass-market, specifically the Shooters since they're the biggest market segment. Rip out RPG elements and replace them with Shooter elements so that they can pull in the "Bang! Bang!" crowds that hate RPG mechanics in the hopes that they'll sell enough units to keep going.
RPG's are dying, but so is the rest of the Industry. Coalescing all gaming down into one genre is just going to create massive gamer fatigue. Most of E3 was a Shooter, with very little difference between them. Making everyone play the same game endlessly is just going to make people quit playing games, just like making people watch the same TV show does. Such as the Reality Show craze which killed the genre by having so many near-identical shows.
The Industry requires 24 months to shift gears, with the next 12-24 months being pretty much all shooters, by the time they realize the full impact of Gamer Fatigue, it'll take them way too long to shift gears and diversify. We're going to see a massive crash, that's very likely to wipe out pretty much all of the familiar names in the Industry. EA and Zenimax are two of the bigger canidates for industry shaking crashes, especially as EA's having a really hard time keeping the NFL license locked down now.
