Umm, Cydia and installer will live hand in hand, much like before the 2.0 jailbreak sensation. Cydia has a MMI source, A Bigboss source and a couple other smaller ones, but pretty much has everything that installer does, or will have. Installer will always be more loosely regulated because sources are so easily made and people just make them to be cool, While cydia has much less, but more secure sources. In turn i'm sure they will both work side by side on 2.0

Also I ran Cydia before 2.0 and it had a installer package for awhile, Meaning that I think we should be looking in cydia for the installer app soon, seeing as installer is just another app.
