I would not risk making any statement regarding performance before either getting any first hand info from the show or before looking at some benchmarks and real-world testcases published by some "independent sources" (e.g. neither Elbox, platon42 or E3B).
At least I would never judge about performance just by looking at some fuzzy videos of a language that I don't speak.
Btw, was there any estimated price mentioned already? This is were it all finally depends on. Just look at Ebay prices for a Blizzard 1260 (up to 250 EUR!).
