TBC lifespan

Is it worth playing and grinding TBC right now if the game dies in 4-5 months ? I dont have a character and i will be starting from level 1 but im not sure if they are not going to release another classic version. Because every time they release a new classic version the whole community starts playing it. The leveling is prob the most boring thing ive ever played in WoW and i just want to Raid and PvP. I cba if they release a new version and i have to level again.
