I read a little more about the 2.5 release. The beta version will come out as a patch for OpenBeta 1.5, turning it into OpenBeta(?) 2.5 and OpenAlpha 2.1 will cease to exist - I guess as far as ED is concerned and 1.5 will remain but unsupported. So I assume by that that we will see 2.5 servers and 1.5 servers, at least for a while, on the DCS multiplayer page.
The stable version of 2.5 will come as a stand alone download. For those of us that might be challenged with available space on their gamer's primary storage device maybe we, as a squad, should decide which version we are going to use? My vote would be for the beta version since it seems that it is always the first to get the latest updates.
