8" Windows Tablets - Buy now or wait for CES?

I'm planning to buy an 8 inch (full) windows tablet. Either the Lenovo Miix2 8 or the Dell Venue Pro 8. But with CES right around the corner, would it be better to just wait for new announcements? Or doesn't it look like there will be any new decent W8 tablet that blows the Lenovo or dell out of the water? (not planning to wait 6 months to be able to buy it either)
