I'm really torn

I recommend waited like 2 months. I hear there is a rumor that google is release a updated gpu Nexus 10. The rumor seems to be spreading.

Yeah, just like the rumor of LG shutting down production on the Nexus 4 spread. A spreading rumor doesn't mean much.
 
Just stating its a rumor that could up being true. Think about it, almost all our Android device news start off as rumors and them become. The whole reason I never bought a Galaxy Note 10.1 is because of a Rumor that Samsung was going to Release a Tablet with Mali t604 instead of the obsessively recycled Mali 400. And some time went by and turns out Rumor totally true. Its not going to hurt him to wait alittle. They might announce some things in March if anything.
