Bright Canopy think otherwise and held their first meeting with Second Life residents on 25th April to explained that this service should be similar to SL Go, but will be web browser based, initially using Chrome. So, if a device or PC can run Chrome then in theory it should be able to use this service as an alternative to SL Go, which ends tomorrow.
Bright Canopy is in closed beta right now, but will be a premium service accepting payment via credit card or Bitcoin, with plans to add Paypal and Linden Dollars after launch.
The service still seems to be a way off from launching, but appears to be the most likely successor to SL Go.
