Question about bi-amping and 7.1

[parklyfe]

at the moment im just using 2 front speakers out of my receiver. i just bi-amped them to the receiver. my onkyo manual says to put one set into the rear speaker inputs and they other into the regular ones i did this.

now for the question, when i buy my side speakers, center, and sub will i have a 7.1 system with just the 5 speakers (2 front ones bi-amped) and the sub or will it still be 5.1 even though they are bi-amped.

thx
