Are first gen roku players locked to software version 3.1? I haven't had an update I'm a while so I checked the forum and it seems we are in the 5s?
Roku 1s do not have the processing power to move up to the interface design of the R2s, R3s and R4s and above. The Software will probably not be updated in the future to add functionality but should a bug develop there could be bug fixes.
That is to say, in development terms, that the R1s are mature products and will not, most probably, see a software update for any reason other than fixes or simple cosmetic changes.
They are not dead but there are features of the R2s and R3s tat the R1s cannot support because of hardware limitations. Future channels might continue to work on the Rs but there will be channels, and already are such, that cannot function on the R1s.
The R1s will continue to be supported but their future as far as new content/channels is limited. Even existing channels may be upgraded on the R2s and up but the R1s will continue to have the older version of the channels. Just guessing I would say that Netflix is one that will move upward with the R2 and R3 but the R1 will not see the new features.
