I have to agree with this as well. These two waves need to hit big in terms of sales... but that having been said, the future waves after 12 & 13 need to be a hit in terms of quality, charascter selection, and new parts, or else DCD is going to seriously steal DST's thunder. And consdering how hot these things came out the gates, up to the waves with the Fantastic Four and Lady Deathstrike, it would be a shame to see the original 2" mega-mini line go by the wayside.
I'm excited for the new Colossus (since I don't have the previous one), Sentry, Beast, Ronin, Shadowcat... but there is so much more Marvel dying to be mini'd. Just the X-Men characters I can think of alone (Angel, Psylocke, Gambit, Jubilee, Banshee, Toad, Pyro, Callisto, "modern" Storm, Mr Sinister, Cannonball, Deadpool, and that's just off the top of my head) could support the next five waves and still have interesting characters to go.
