@9to5mac seems iTunes Match is coming to Poland. Apple updated their "ToU" for the Polish iTunes Store with iTunes Match info on 18th.—

We received several tips that Apple started rolling out the iTunes Match service in Poland, Hungary, and possibly a few other unconfirmed markets. Apple’s official list of availability for iTunes Match by country has not been updated to include Poland, Hungary, or any additional markets, but currently lists 55 countries with access to the service. Local reports claim the service is available for 24.99 euros in Hungary, which is on par with pricing in other markets.
Let us know in the comments if you notice iTunes Match available in your country.
