I am far less optermistic, Intel have lost a lot of money on this and they are really late, by the time anyone see's this in the west if at all then who is going to want to buy them against the 4000 or 7000 series from nvidia and amd.
In reality i expect a limited run of cards and if they don't sell then it'll get shutdown, oem's are the most likely to buy them as they get great deals, but Intel while they might have a lot of man power and funding are not in the biz of losing money.
For battlemage to even get going fully they will already be behind again, they are not about to commit to the road map for a decade to get where they want to be if it doesn't make them money then forget it.
Intel are not going to be the hero, they were just the hero you hoped for.
let alone the drivers they need some kind of internal communication to get them right cause they are all over the place only need to watch a few YT videos to see that rather than cherry picked benchmarks or did we forget about the external reviews they paid for with the cpu's a few years back ?
