Buy lieon 52/24/52 or 52/32/52

I’m wondering what to do, to go buy a liteon at 24X RW or wait for the 32X RW. The only thing that matters me is that when the 32X RW disks are available, will I be able to rewrite them with the 52/24/52 liteon or any 24X RW recorder?The speed doesn’t matter me.I also know tha RW media 10-12X are called high speed and the 24X ultra speed.The 32X media how will be called and the 16X some recordes support is high or ultra speed?
