If I buy Warcraft 3 now, will I get access to classic?

A while ago, I bought classic Warcraft 2 and absolutely loved it. The only reason I bought Warcraft 2 was because classic Warcraft 3 was unavailable.

But now classic version is available to those who currently own the reforged version. I wander what about those who do not currently have Warcraft 3, and choose to buy it now, will they also get access to the classic version?

More importantly, do you guys think classic will be available for a long time or just a short period? (I ain't paying for an inferior product just to get limited access to a legendary product lol)
