This question probably asked in a different way, but want to 100% make sure, 
 
I got a EVGA 1080ti a month ago and returned it right after 2080ti was announced as i have missed 14 day deadline to register with EVGA.
I did pre-order an 2080ti XC ultra and (i can cancel it anytime), but it seems like ICX2 version will be released later.
 
If i'm buying an 1080ti today (from egg), will i be eligible for step up within 90 days to 2080ti?  Is there any 'stock' risk, within 90 days and  i will be able to step up atleast to a XC ultra in case my desired card is not available?   Do i have to buy extended warranty or its optional?

Hello mmuthiah! Currently, we do not have any 20-series graphics cards available for Step-Up but we estimate they may be added after they are released on or about September 20th. If you were to purchase a graphics card today, you would still be within the 90 day window for Step-Up on 9/20. Please keep in mind that generally only reference models of cards are added to Step-Up and higher-end cards are usually not added to the Step-Up inventory. As long as you register the 1080Ti within 14 days of your purchase date then you do not need to purchase an extended warranty for Step-Up.
