Purely concerned from Sony's announcement of haptics etc for the DS5 - don't want my Elite 2 to be old news from a featureset perspective after 1yr.
I'm hyped about the haptics in the DS5, but I'll believe they're a game changer when I see the receipts. The DS4 touchpad was abandoned quickly, as were the gyro controls in the Sixaxis. Heck, even the Switch doesn't really utilize the "HD Rumble" feature for most new games.
I believe they've stated that the Elite V2 will be forward-compatible. We won't likely see a V3 for at least a few years.
