I've been thinking of getting a multi region blu ray player for a while and have recently been looking again. We don't have a 4k TV and have no immediate plans to get one at the moment but who knows when this will change. Therefore I'm wondering if it's worth just going for a 4k multi region player now to future proof it (TPS offer a 3yr warranty). Will there be any other benefits (audio etc, I have a Yamaha YAS-107 soundbar) if I get a 4k player now? If I do I'm looking at something like a Panasonic UB-450EB. Or am I better off either just going for a standard multi region player or hanging on until I do have a 4k TV? I currently have a Sony Bdp-s3500, need a player with WiFi as the router is upstairs.
