The Fruits Basket treatment was sorta an experiment... failed. ;p Seems consumers are more sensitive to price/DVD than price/ep. Don't expect FUNi to try that again any time soon.
Besides, if CN airs it (despite what IGN says, it's not definite until CN announces it - remember Gundam Zeta and GitS

AC), the consumer demand for it will increase. Typically, less demand -> more eps/DVD to entice buyers, so more demand -> don't expect 6 eps/DVD when enticement not needed. (There wasn't much built-in demand for Fruits Basket, more obscure and shoujo anime; s'why it got 6 eps/DVD.)
Laters. =)
