forever subscription, you say?

They already have a forever mouse - its called Logitech MX518 - at this point its over 18 years old, and beside some small paint deficiencies it has no other issues. And it was used quite heavily - it survived years of intensive button mashing in Diablo2 and many other games...

To be fair they only said having a subscription for the accompanying software was a 'possibility', not that it would need one, and that it would be likely to be in the ~$200 price range, and with upgradeability and repairability in mind, as well as reliant on software updates.

Honestly depending on how much they lean toward the subscription and/or software update reliance having a mouse designed to last a lifetime and be upgradeable and repairable would be nice, even at a rather higher price point.
