Blu-ray players' future compatability

[madmax141]

hey guys, im brand new to this forum and just had a question before i spend up to 600$ on a blu ray player. Im looking to get either the samsung bd-p1200 or the pasonic DMP-BD10Ak, however i know that BD-J 1.1 and BD-J 2.0 are coming fairly soon. I've read many things about how the sammy, with firmware upgrades, could play the movie on br-j 1.1/2.0 but just not the extra features, so i guess the pasonic can do the same. But what about Java scene selection, or maybe i couldn't even play a movie because of a future advanced java start menu?

so i guess to sum that all up... will either players ever become so obsolete that they cannot play future blu ray movies?! (i dont care about extra features, and i also apologive in advance if this subject has been touched on before)
