I have the same question. I would like to transition my house away from WMC7. I have tried XBMC and now I would like to try MP. The dilemma is MP1 or MP2. Obviously MP1 is stable but I don't want to put in a lot of effort only for it to be wasted when MP2 comes out. Perhaps starting with MP2 alpha is a better idea or will a migration path be provided?
I'm still using BeyondTV and MediaPortal 184.108.40.206 with WinXP......yea I know, but it works and it keeps the wife happy. Soon I plan to replace my aging system and I was going to switch to WMC because of cablecard support, but I prefer a non-M$ solution....preferably MP. I eagerly await the arrival of MP 1.3 !!!
