Well, the way I look at it is this:
Can a Wiz7/Clr3/MysT10 gain Epic Spellcasting?
Can a Clr7/Wiz3/MysT10 gain Epic Spellcasting?
The answer to both is yes, as the requirements for Epic Spellcasting is to have access to 9th Level Spells, not 20th Caster Level.
This is not in doubt. But the requirements to actually learn or cast Epic level spells are so high, no "low" Epic character will be using them soon.

Now, instead hit 20th Level as Clr5/Wiz5/MysT10 and take MysT from there on; At 22nd Level, you qualify for Epic Spellcasting (although you don't get a Feat until 24th), and at 25th Level you've got the full Spell output of a 40th Level character (Clr20/Wiz20). Add in the standard assortment of stat enhancers, and it just gets uglier from there.
EXCEPT, compared to a single classed caster, you have 3 lower caster level, for determining range, effect, SR-penetration, combined with what is probably a lower Prime stat (assuming point buy) as any stat enhancement can be gained by the single classed user.
ALSO, you WILL have FEWER slots of higher than 9th level spells: Improved Spell Capacity adds an increased slot to ONE of your spell casting classes. The single classed spellcaster WILL be gaining MORE epic feats.
Thus, IIRC, a 25th level Wizard will have 5 more feats (2 of them epic!) than the Clr 5/Wiz 5/MT 15.
So if we consider that those two epic feats where Improved Spell Capacity, the 25th level wizard now has at least TWO spell levels over and above the MT. The Wiz also has more Metamagic feats to properly utilise these spell levels as well.
Notice that the Clr 5/Wiz 5/MT 11 CANNOT take Improved Spell Capacity due to inability to cast 9th level spells! Thus increasing even further the distance in high power spell casting.

Is the class overpowered? If your game ends at 12th-15th Level, possibly not, particularly if you attach enough in-setting hooks to the class (organizations, duties, rivalries, etc.). However, reduce the hooks or take this into Epic, and it's way over the top.
It isn't overpowered, there are a lot worse PrC out there. Falling behind three caster levels prior to epic level is a big handicap. Falling behind in highest Spell Level Slots at Epic is also a major Hinder. Admittedly I'm not sure as to how much considering the large number of spells available, that is something that needs to be tested.

So, is 3.5 being written to be even more powerful than 3.0 seems to favor, or simply short-sighted? I don't know. I do know that I'm going to go over the SRD with a fine-tooth comb before I put out any money for it.
Yeah right. Nerfing Haste, Harm, realigning the core classes slightly is REALLY addding to the power base...
