Don't want to be the bubble-burster here but don't expect a solid two-way game from Zhilkin. Now, do I think he provides more offensive upside for the team? Yes. Zhilkin is a nifty, highly skilled one-dimensional scorer who was stuck on a lousy Guelph team so I absolutely expect his numbers to rise.
Fun Fact: He played his minor hockey with the Toronto Marlies with Arcuri before Arcuri left to Don Mills Flyers in his draft year. Their play styles were almost too similar to ever create solid chemistry back then - not sure if that plays a factor years later - would be interesting to see.
Long story short, I think it's a decent move - but an over-pay, especially if you were hoping for 200-foot play. Scoring will certainly be there though.
