Are Transformers still going strong? Options

[Onyx Minor]

IDW has had the Transformers franchise for awhile, but how are things going? Let's take us for a look at the numbers from the beginning. What trends do you see?

Based on information from this source:

Here are some numbers to get started:

Then and now:
30 TRANSFORMERS INFILTRATION #1 45,468 (January 2006)
146 TRANSFORMERS DEVASTATION #5 13,185 (February 2008)

The trend:
68 TRANSFORMERS INFILTRATION #4 28,835
138 TRANSFORMERS ESCALATION #1 20,625
148 TRANSFORMERS DEVASTATION #1 15,704

Spotlights
159 TRANSFORMERS SPOTLIGHT HOT ROD 14,133
155 TRANSFORMERS SPOTLIGHT MIRAGE 11,046
152 TRANSFORMERS SPOTLIGHT GRIMLOCK 11,411

Not even the movie brought the numbers:
88 TRANSFORMERS PRIME DIRECTIVE MOVIE PREQUEL #1 23,658
114 TRANSFORMERS PRIME DIRECTIVE MOVIE PREQUEL #2 18,039
114 TRANSFORMERS PRIME DIRECTIVE MOVIE PREQUEL #3 18,000
127 TRANSFORMERS PRIME DIRECTIVE MOVIE PREQUEL #4 17,306

109 TRANSFORMERS MOVIE ADAPTATION #1 (Of 4) 18,071
123 TRANSFORMERS MOVIE ADAPTATION #2 (Of 4) 16,204
121 TRANSFORMERS MOVIE ADAPTATION #3 (Of 4) 16,247
122 TRANSFORMERS MOVIE ADAPTATION #4 (Of 4) 16,210

From what we can see, their numbers are less than 1/3 what they started out to be. What do you guys think? Are Transformers losing some of their momentum? If so, what is the cause?
