If you're plan is to have M22's or M60's in the front, then you would be better suited having a pair of M2i's. They'll match the M22 or M60 better down the road.
When you say "rear", do you indeed mean rears, as in a 7.1 configuration or "surrounds" as in a 5.1 config? If you plan on sticking with 5.1, I'd skip the M3ti and M2i all together. Save up to buy those M22 or M60 mains first, and when you get the surrounds, get the QS8's. They're the best surround speaker I've heard.
If you are building a 5.1 system, wait the month or two, and get the M22's or M60's first. Then the VP150 center or QS surrounds. You'll not regret it. That's assuming your ultimate goal is 5.1.
If you're planning on 7.1, then like I said, I think the M2i would be a better match for you.
